Florida Atlantic University’s head football coach Lane Kiffin is known for letting his feelings fly. Now he’s be fined for it following a tweet tagging Conference USA’s Twitter account with a shot at their officials.

After a tough 36-31 loss to Marshall, Kiffin posted a meme of blind referees and tweeted it directly to “@ConferenceUSA” on Saturday night. Conference officials didn’t take too kindly to the attack, fining Kiffin $5,000 and reprimanding him for violating the league’s sportsmanship policy.
