Swansea City and Hull City were fined £20,000 each following a mass confrontation between their players during a Premier League match this month, the Football Association said on Wednesday.
Swansea's Ashley Williams clashed with Hull's Tom Huddlestone and Yannick Sagbo in the closing stages of their 1-1 on December 9, sparking a fracas between both teams' players.
"The clubs each admitted a charge of failing to ensure that its players conducted themselves in an orderly fashion," the FA said in a statement.
Hull, who are 12th in the Premier League, travel to West Bromwich Albion on Saturday and 10th-place Swansea play Everton on Sunday.
