Discipline Statistics

Discipline statistics measure how frequently players commit fouls or receive disciplinary sanctions during a match. These metrics help evaluate:
  • Aggressiveness in defensive play
  • Risk-taking behavior
  • Compliance with match rules
  • Impact of disciplinary actions on team performance
Disciplinary events are recorded whenever a player commits an action that results in:
  • A foul
  • A caution (yellow card)
  • An expulsion (red card)
Each disciplinary event records:
  • Player committing the foul
  • Opponent involved
  • Type of sanction
  • Location of the incident
  • Match time

​
Discipline Metrics

Fouls Committed

Total number of fouls committed by the player against opponents.

Fouls Awarded

Total number of fouls received by the player or team from opponents.

Fouls Committed In Defensive Third

Total number of fouls committed within the defensive third of the pitch.

Fouls Awarded In Offensive Third

Total number of fouls won by the team in the attacking third of the pitch.

Yellow Card

Total number of yellow cards received by the player.

Second Yellow Card

Total number of second yellow cards received, resulting in expulsion.

Red Card

Total number of direct red cards received by the player.

Red Card Total

Total number of expulsions including both direct red cards and second yellow cards.

​
Total Expulsions

A player can be sent off either by receiving a direct red card or by receiving two yellow cards in the same match. Red Card Total=Red Card+Second Yellow Card\text{Red Card Total} = \text{Red Card} + \text{Second Yellow Card}

​
Foul Balance

Foul balance compares the number of fouls committed versus fouls received. Foul Balance=Fouls Awarded−Fouls Committed\text{Foul Balance} = \text{Fouls Awarded} - \text{Fouls Committed} A positive value indicates the player wins more fouls than they commit.

​
Card Rate

Card rate measures how frequently a player receives disciplinary sanctions. Card Rate=Yellow Card+Red CardMinutes Played\text{Card Rate} = \frac{\text{Yellow Card} + \text{Red Card}}{\text{Minutes Played}} This metric helps assess disciplinary risk relative to playing time.

​
Relationship Between Discipline Metrics

Disciplinary events follow these relationships. Total Cards=Yellow Card+Red Card+Second Yellow Card\text{Total Cards} = \text{Yellow Card} + \text{Red Card} + \text{Second Yellow Card} Red Card Total=Red Card+Second Yellow Card\text{Red Card Total} = \text{Red Card} + \text{Second Yellow Card}

​
Tactical Interpretation

Discipline statistics help analysts evaluate:
  • Defensive aggression
  • Tactical fouling
  • Risk management
  • Player discipline under pressure
Players with high foul counts or frequent cards may pose a disciplinary risk, potentially leaving their team disadvantaged during crucial moments of the match.

​
Example Discipline Scenario

Defender → Late Challenge → Referee Decision Foul → Free kick awarded to opponent Yellow Card → Player cautioned Red Card → Player sent off

​
Spatial Context

Fouls and disciplinary actions occur throughout the pitch but are particularly critical when they occur in:
  • Defensive third
  • Dangerous free kick zones
  • Penalty area

Defensive Actions

Statistics describing tackles, interceptions, and other defensive interventions.

Set Pieces

Many fouls result in set piece situations such as free kicks and penalties.

Possession

Possession loss or recovery can influence defensive fouling situations.

Goalkeeping

Goalkeepers may also receive disciplinary actions in certain situations.
