"It was stupid and inappropriate," Ryan said in a statement issued through the Jets. "I wouldn't accept that type of behavior from one of the coaches or players and it's unacceptable from me. I apologize to the Jets organization, the National Football League and NFL fans everywhere."
Jets general manager Mike Tannenbaum criticized his coach.
"Rex showed extremely poor judgment and his conduct was inappropriate," Tannenbaum said. "He knows he was wrong, has apologized and we have accepted his apology. Any other actions regarding this incident will be addressed internally by the organization."
It is uncertain whether Ryan will be fined by the team, the league or both. Titans owner Bud Adams was fined $250,000 for making a similar obscene gesture at Bills fans during a game in Nashville in November.
NFL vice president Greg Aiello said the league will investigate the incident.
Ryan, who was in Miami to visit with his players at a Pro Bowl practice, made the gesture at Miami resident David M. Hildenbrand and his friends, according to a report in the Miami Herald. It is not known if Ryan was provoked.
"I'd like to thank everybody here in Miami. I know they love me," Ryan said Saturday night in an interview with Strikeforce, the company that hosted the event featuring former NFL running back Herschel Walker's victorious MMA debut. "I want to just tell everybody in Miami, 'Hey, we're coming to beat you twice next year,' " Ryan said as he was being booed.
The Jets lost twice to the Dolphins in 2009.
"It's one of those things where you never know where a camera is going to be,'' Mangold said. "It's unfortunate. You have to move on. I think more so now, as technology is evolving with camera phones, it can be anywhere. So you have to stay on your 'A' game.''
Said Revis: "You got to understand, we're human. We still have feelings and people get angry. It's just that you have to control it sometimes. The best thing is to apologize and then move forward."
