The NFL fined Tampa Bay Buccaneers quarterback Jameis Winston $12,154 for his poke that led to a suspension for teammate Mike Evans, a league source told ESPN's Adam Schefter.

Winston pushed New Orleans Saints cornerback Marshon Lattimore's helmet during an altercation in Sunday's game. Lattimore shoved Winston in retaliation, leading Evans to hit Lattimore in the back and pounce on the cornerback when he hit the ground.

Evans' actions drew a one-game suspension from the NFL, which will cost him $40,588.23 in pay.

The amount for all fines is determined by the league's schedule of fines. In Winston's case, he was "making a threatening gesture toward an opponent." When the fight broke out, Winston had already left the game with a shoulder injury.

The Bucs quarterback said he was sorry Wednesday for his role in the fracas.

"I just want to apologize on behalf of my teammates and Mike Evans for the incident that happened in the Saints game. That's something I can't do in the heat of the moment," Winston said. "My competitive nature [took over]. Obviously I can't come off the field and make any gesture toward an opponent, let alone touch them. I can't do that, so I apologize for that."

Winston, who is expected to miss at least two weeks with a sprained AC joint in his right shoulder, had said that he expected to be fined.

Coach Dirk Koetter called the behavior "totally unacceptable," especially from two team captains, adding "That goes against everything you would want your team to stand for. Those guys know that."

Koetter also suggested that both players should have been ejected.

"Jameis cannot, under any circumstances, come off the sideline when he's not even playing in the game," Koetter said. "And trash talking is trash talking, but to go out and tap another player, touch another player, whatever you want to call it at all on the field -- that's inexcusable."
