A Red card in football is a game-changing penalty that requires the player to leave the field immediately. Given for serious fouls or misconduct, it ensures the safety and fairness of the game. A team that receives a red card in football must continue the match with one fewer player, often leading to a tactical disadvantage. This penalty emphasizes the importance of discipline, making the game more competitive and respectful. It serves as a deterrent against dangerous behavior, reminding players that the integrity of football is always the top priority.
