Manchester City has been penalized 14,000 euros (£11,910) for "improper team behaviour" during last month's Champions League tie with Atletico Madrid.
After a scoreless second leg of the quarter-final, City advanced to the last four.
The sending-off of Atletico defender Felipe for a foul on Phil Foden prompted a brawl involving both sets of players and coaching staff.
Atletico, however, have not been sanctioned by Uefa's disciplinary committee.
Former City defender Stefan Savic attempted to tug Jack Grealish's hair during the altercation before confronting the England striker following the game.
Before successfully appealing Uefa's ruling, Atletico had been ordered to shut part of their stadium ahead of City's visit.
In reaction to "discriminatory behavior" by Atletico fans during the first leg in Manchester, Uefa ordered Atletico to shut at least 5,000 seats at the Wanda Metropolitano.
After a plea to the Court of Arbitration for Sport, the sentence was reversed.
