Lacrosse Scoreboard: Field, Box and Every Clock the Scorebug Has to Run
What a lacrosse scoreboard overlay must display, why field and box lacrosse need different configurations, and the penalty rule that makes lacrosse graphics genuinely hard.
A lacrosse scoreboard graphic must show the score, the quarter or period, the game clock, the shot clock, any active penalty clocks and a man-up or man-down indicator. In a live broadcast the same graphic is also called the scorebug. There is no single lacrosse scoreboard, because field and box lacrosse are effectively different sports for a graphics package: different period structures, different shot clock lengths, different penalty durations, different numbers of players.
The "one lacrosse scoreboard" idea is therefore wrong before you start drawing. What you want is one data-bound bug with a variant setting. This page sets out what each variant has to display and where the timing gets difficult, alongside the master scoreboard guide covering how scoreboard graphics work across every sport.
What a lacrosse scoreboard must show
| Element | Why it matters | Source of data |
|---|---|---|
| Score | High-scoring sport, so digits change often and must never jitter | Goal events from the scoring app or a feed |
| Period label | Field runs quarters, box commonly runs periods, so the label is variant-driven | Match configuration and period events |
| Game clock | Counts down, stops on every dead ball, needs tenths in the closing seconds | Clock start, pause and resume |
| Shot clock | A second clock viewers read constantly, and the length differs by competition | Shot clock start, reset, violation |
| Penalty clocks | Several can run per team at once, and some end early on a goal | Penalty start, expiry, early release |
| Man-up / man-down | The single most important context in lacrosse, derived not entered | Derived from active penalty counts |
| Timeouts remaining | Allowances and reset rules differ by league | Timeout used events, reset at period boundaries |
| Team names and logos | Long club names must ellipsis rather than break the layout | Team record |

Field and box are not the same scoreboard
The two codes share a name and little else from a graphics point of view. Build one bug for field lacrosse, point it at a box game, and it renders the wrong number of periods, the wrong period length, a shot clock roughly double the correct length and a lineup card with four players too many.
| Field lacrosse | Box lacrosse | |
|---|---|---|
| Period structure | Four quarters, commonly 15 minutes | Commonly three periods; length varies by league, 12 and 20 minutes both in use |
| Shot clock | Set per competition, commonly 60 to 80 seconds | 30 seconds |
| Players on the surface | 10 a side: three attack, three midfield, three defence, a goalkeeper | 6 a side: five runners and a goalkeeper |
| Man-up states | Typically 10 v 9 and 10 v 8 | Typically 6 v 5 and 6 v 4 |
| Period label | Q1 to Q4, then OT | P1 to P3, then OT |
None of that should be two graphics packages. Period count, period length, shot clock length, player count and the lineup position codes are all values. Treat them as artwork and you maintain two of everything for the rest of the sport's life.
The clock is the hard part
A lacrosse bug runs three kinds of clock at once and they do not stop together in the same way. Game clock and shot clock both freeze on a dead ball and on a timeout. Penalty clocks only tick while the game clock runs, so they pause with it and carry across a period break if time remains.
The shot clock is the second thing a viewer looks at, so it has to be legible at a glance and it has to be right. It resets on a change of possession, and under some rule sets a shorter reset applies when the ball stays with the attacking team after a save or a defensive touch, so a reset is not always back to the full number. Some leagues also switch the shot clock off late in a game, and an overlay still counting down after the officials have turned it off is worse than one showing nothing.
The rule that makes lacrosse graphics hard: most penalties are releasable. If the team on the man-advantage scores, the penalised player comes straight back on and the penalty clock ends early. So a goal event has to reach across and cancel a running countdown, then flip the man-up indicator, in the same moment the score changes. Non-releasable penalties, including unsportsmanlike conduct and the longer personal fouls, run their full time no matter how many goals go in.
Get it wrong either way and it shows immediately. Cancel a non-releasable penalty on a goal and the bug says even strength while the broadcast shows a man-up offence. Leave a releasable one running and the bug claims an advantage that ended two plays ago.
Two smaller details are worth building in from the start: tenths of a second in the closing seconds of a period, because lacrosse ends on buzzer-beaters and a bug reading 0:00 while the ball is in the air looks broken, and tabular figures on every clock, so digits do not shift sideways when 10 becomes 9.
Scoring events and what the bug does
Lacrosse scores far more often than football, so goal graphics need to be quick and the distinctions genuine. The ones worth carrying:
- Assisted goal - scorer, number, assist, quarter and time.
- Unassisted goal - labelled UA, but only when the goal was genuinely unassisted, never when an assist simply was not captured. If your data cannot tell those apart, do not print the label.
- Man-up goal - tagged from the penalty state at the moment of the goal, not entered separately. It is also the event that may release a penalty and end the advantage.
- Man-down goal - the rarer and more newsworthy version, scored by the short-handed team.
- Goalkeeper goal - rare enough to deserve its own badge.
- Shot clock violation - a turnover overlay, which must not fire if the shot beat the buzzer.
As on any bug, the score digit should change before the goal graphic plays, or the two disagree on screen for half a second and viewers notice.
Penalties, man-up and man-down
Lacrosse penalties come in two families, and the bug has to distinguish them because they carry different durations and different release behaviour.
| Penalty | Typical duration | Examples |
|---|---|---|
| Technical foul | 30 seconds | Holding, warding, offside, illegal procedure |
| Personal foul | One, two or three minutes by severity | Slashing, cross-check, illegal body check, illegal stick, unsportsmanlike conduct |
| Ejection | Player out for the match, team short for a fixed period | Fighting, third personal foul, match misconduct |
Show each active penalty as its own chip with player number, penalty family and time remaining, and mark non-releasable ones clearly so a commentator can see at a glance that a goal will not end it. Several can run for one team at once, which is what produces a two-player advantage.
The man-up and man-down indicator is derived, never entered. It sits beside the team name, shows the differential when a team is two up, and shows nothing when offsetting penalties leave the sides even. It has to flip the instant a penalty expires or releases: a stale advantage indicator is the most obvious error a lacrosse bug can make.
Extensions: the stats worth putting on the bug
An extension is a pop-out panel attached to the bug, fired on a milestone or an operator cue, and it can carry a sponsor banner. The lacrosse ones are strong because the sport has stats nothing else has:
- Faceoff win percentage - the faceoff specialist is a position in its own right, and the number genuinely predicts possession.
- Goalkeeper save percentage - saves against shots faced, recalculated on every save and goal conceded.
- Points leaders - goals, assists and points together, since lacrosse counts scoring as points.
- Ground balls and caused turnovers - the possession stats that decide close games and never reach a generic overlay.
- Lineups by position code - attack, midfield, defence, long-stick midfield, short-stick defensive midfield, faceoff specialist and goalkeeper for field, a shorter list for box.
How LIGR drives a lacrosse scoreboard
LIGR's lacrosse scoreline is built: a Rive design bound to live match data in Fuse, LIGR's graphics configuration and publishing engine, which connects designs to a live production without code. Because the bug is data-bound rather than drawn, field and box are configuration: shot clock length, period count, period length and player count are variables on one scorebug, not a redraw.
The data question is the one every sport below the top tier faces. There is no commercial lacrosse feed at most levels, so the LiveScore app is the feed, a lacrosse scoreboard app run from a phone or tablet. An operator taps a technical foul against a player, and the app knows the duration, starts the countdown and flips the opposition to man-up. Every event is timestamped as it is entered, which is what makes faceoff percentages, save percentages and automated highlights possible afterwards. Where an official feed exists, LIGR takes it instead.
Game Plans fires penalty widgets and break playlists off the same event stream, the Control Room gives an operator manual control where a producer wants one, and auto-mode runs a match with no operator at all. It is the same event model that carries a full season of DAZN National League football, 640 or more matches, and the same second-clock discipline LIGR already runs in basketball.
Frequently asked questions
What is a lacrosse scoreboard overlay?
A lacrosse scoreboard overlay is the graphic a stream or broadcast lays over the video to carry live match state, and in production it is also called the scorebug. It has to show the score, the quarter or period, the game clock, the shot clock, every active penalty clock and a man-up or man-down indicator, because a lacrosse side can be short one or two players at any moment.
What does a lacrosse scoreboard need to show?
A lacrosse scoreboard needs the score, the quarter or period, the game clock, the shot clock, any active penalty clocks and a man-up or man-down indicator, with timeouts remaining a useful addition. The penalty clocks and the man-advantage indicator separate lacrosse from a generic overlay, because a lacrosse team can be short-handed by one or two players at any point.
Is a field lacrosse scoreboard the same as a box lacrosse scoreboard?
No. Field lacrosse runs four quarters, 10 players a side and a shot clock of a minute or more. Box lacrosse commonly runs three periods, six players a side and a 30-second shot clock, with period lengths that vary by league. The right answer is one data-bound scorebug with a variant setting, not two graphics packages to maintain.
How long is the lacrosse shot clock?
Box lacrosse uses a 30-second shot clock. Field competitions set their own, substantially longer figure, commonly in the 60 to 80 second range, because a field possession includes clearing the ball as well as the settled offence. Since the number is not consistent across competitions, a lacrosse scoreboard should take shot clock length as a configuration value rather than hard-coding it.
What does man-up or EMO mean on a lacrosse overlay?
Man-up, often shown as EMO for extra-man offence, means the opposition has a player serving a penalty, so the attacking team has a numerical advantage. Man-down, or EMD, is the same situation from the penalised side. The indicator should be derived from the active penalty clocks rather than entered by an operator, so it can never disagree with the countdowns beside it.
What is a releasable penalty and why does it matter for graphics?
A releasable penalty ends early if the team with the man-advantage scores, so the penalised player returns immediately. Non-releasable penalties run their full time regardless. For a scorebug that means a goal event has to cancel a running penalty clock and flip the man-advantage indicator in the same moment the score changes, and know which penalties are exempt.
How many penalty clocks can be on screen at once?
More than one per team. Two concurrent penalties against the same side produce a two-player advantage, which the indicator should show as a differential rather than a plain man-up pill. Show each penalty as its own chip with player number, type and time remaining, ordered so the next player back is at the top, and mark non-releasable ones distinctly.
Can you run lacrosse graphics without a data feed?
Yes, and at most levels you have to, because no commercial lacrosse feed exists below the top tier. LIGR's LiveScore app becomes the feed: an operator enters real match events on a phone or tablet, the graphics update automatically, and each event is timestamped for stats and highlights. Where an official feed exists, LIGR takes it and drives the same graphics.
