The laws of the game lay out several offences worthy of a red card. Here are some of the most common scenarios:
Violent Conduct: Football is a physical sport, but there's a line between fair play and downright dangerous behaviour. Striking, kicking, or elbowing an opponent crosses that line. These actions put other players at risk and are punished severely.
Serious Foul Play: Tackles are part of the game, but reckless challenges that endanger a player's safety can result in a red card. A studs-up challenge, a two-footed tackle, or a forceful tackle from behind are all examples of fouls worthy of a sending off.
Denying a Goalscoring Opportunity: Imagine a striker clear through on goal, only to be brought down by a desperate defender. This is a clear denial of a goalscoring opportunity (DOGSO), and the offending player can expect a red card.
Spitting: Spitting at an opponent or official is deemed unacceptable behaviour in football, showing a complete lack of respect for the game and its participants. This almost always results in a straight red card.
Two Yellow Cards: Yellow cards serve as warnings for less serious offenses. However, if a player accumulates two yellow cards in the same match, they are automatically shown a red card and sent off.
