Yellow cards are often issued for minor infractions or tackles that appear worse in real-time. Unlike red cards, there is currently no formal review or appeal process for these bookings in football. Receiving a yellow card significantly impacts a player's defensive strategy and can lead to a second yellow, resulting in a numerical disadvantage. Furthermore, accumulating a certain number of yellows triggers automatic one-match suspensions, irrespective of the foul's severity. These bans can be detrimental, especially if a key player misses a crucial fixture due to seemingly soft bookings. The absence of a review mechanism for yellow cards remains a significant point of discussion in the sport.
