what does a red card in champions league mean
Fouls and misconduct (association football) Misconduct will result in the player either receiving a caution (indicated by a yellow card) or being dismissed ("sent off") from the field (indicated by a red card).[1]:38 A dismissed player cannot be replaced; their team is required to play the remainder of the game with one fewer player. A second caution results in the player being dismissed. The referee has considerable discretion in applying the Laws; in particular, the offence of unsporting behavior may be used to deal with most events that violate the spirit of the game, even if they are not listed as specific offences.[1]:123
