Ryan was caught on camera appearing to shout a profanity at someone on the Steelers or on the officiating crew as he walked to midfield when the game ended.
The Jets won 20-13, but in the final minute Pittsburgh safety Mike Mitchell leaped into the Jets victory formation during a kneel down, something that did not sit well with multiple Jets players or Ryan, who called the play "bush league."
''Emotions run high in games,'' he said on Monday. ''Sometimes it's best to ... what happens on the field stays on the field. That's where it stems from. It's a very emotional game. Obviously, I've got to do a good job of controlling my emotions. Things happen. I'm sorry if I offended anybody.''
This is the third time Ryan has been fined for using profanity. In 2011, he was fined $75,000 for cursing at a fan at halftime, and in 2010 he was fined $50,000 by the Jets for making an obscene gesture at a fan at an MMA event.
New York's win over the Steelers snapped an eight-game losing streak and moved the Jets to 2-8 on the season. They have a bye in Week 11.
