Cutler was fined as a result of verbal abuse toward the back judge, which drew an unsportsmanlike conduct penalty in the Bears' 41-21 loss to the Cardinals. The Bears (4-5) have lost four of their past five games.
Acquired in an offseason trade from Denver, Cutler leads the league in interceptions (17) after throwing five in Thursday's 10-6 loss in San Francisco. His 76.0 quarterback rating is among the lowest in the league.
Meanwhile, Bears defensive tackle Tommie Harris was fined $7,500 for unnecessarily striking an opponent. He was ejected just 65 seconds into the game for slugging Cardinals offensive tackle Deuce Lutui.
Harris later apologized.
