Hull City have been fined £40,000 and Arsenal £20,000 following a mass fracas during their Premier League game at the Emirates Stadium in December.
Players from both sides became embroiled in a melee on the stroke of half-time during a game on December 19 which the Gunners went on to win 3-0.
Arsenal midfield Samir Nasri appeared to stamp on Richard Garcia's foot to spark the flashpoint and the FA has taken action in the form of fines for both clubs.
"At a Regulatory Commission hearing this week, Arsenal and Hull City were fined for failing to control their players during a match at the Emirates Stadium in December," read an FA statement.
"The clubs were charged in relation to a mass confrontation between players from both sides.
"Hull admitted the charge. Arsenal denied the charge but the commission found it proved."
