Several players, including Arsenal's Kai Havertz, have already accumulated yellow cards, with five players entering the third round of matches just two cautions away from a suspension. Additional suspensions can occur at six, eight, or ten yellow cards, with a one-match ban for each even number above four.
Understanding these suspension rules is crucial as they can significantly impact team strategies and player availability in critical matches. As the tournament progresses, monitoring player cautions will be essential for teams aiming for success in the knockout stages.
