Norwich City and Sunderland have been fined £30,000 by the Football Association (FA) after failing to control their players during their Premier League encounter on April 16.
The clubs were charged by the FA in relation to an incident in the opening five minutes at Carrow Road that saw players and staff react furiously to a challenge from Robbie Brady on DeAndre Yedlin.
