The NFL is looking into a YouTube video that appears to show New York Jets coach Rex Ryan using an obscenity while angrily responding to a fan during halftime before the team's 37-16 loss to the New England Patriots.
NFL spokesman Greg Aiello says Monday that the league is aware of the 48-second video, which shows the Jets walking off the field Sunday night.
When Ryan appears, someone is heard yelling, "Hey, Rex, Belichick is better than you," referring to Patriots coach Bill Belichick.
Ryan looks up and tells the fan to "shut up" while also using an obscenity.
Ryan was fined $50,000 by the Jets in 2010 after he was caught on a cellphone camera giving the middle finger to a fan during a mixed martial arts event in Florida.
