Union of European Football Associations, UEFA has modified yellow card rule in UEFA competitions. This will reduce the rate at which players miss important matches due to suspension from yellow card offenses. The European football's governing body has decided to wipe out players' bookings after the quarter-finals of club competitions.
UEFA said in a statement, "Following a recommendation by the UEFA Club Competitions Committee - in order to implement in UEFA club competitions a rule which is already in force in the UEFA European Football Championship - the Emergency Panel decided that, as of this season, all yellow cards from the beginning of the group stage will expire on completion of the quarter-finals. Bookings will therefore not be carried forward to the semi-finals."
