what happens if someone gets a red card in the world cup
2014 FIFA World Cup disciplinary record Any player sanctioned with a red card was sent off from the pitch and could not be replaced, forcing his team to play a man fewer. Furthermore, the player was automatically banned from his country's next match, whether via a straight red or second yellow. After a straight red card, FIFA conducted a hearing and considered extending this ban beyond one match. If the ban extended beyond the end of the World Cup finals (i.e. if a player was sent off in the match in which his team was eliminated), it had to be served in the team's next competitive international match(es).
Offside (association football) There is no offside offence if a player receives the ball directly from a goal kick, a corner kick, or a throw-in. It is also not an offence if the ball was last deliberately played by an opponent (except for a deliberate save). In this context, according to the IFAB, "A ‘save’ is when a player stops, or attempts to stop, a ball which is going into or very close to the goal with any part of the body except the hands/arms (unless the goalkeeper within the penalty area)."
