As the Jets walked off the field following their 37-16 loss to the New England Patriots on Sunday night, a fan yelled at Ryan, “Hey, Rex, [Patriots Coach Bill] Belichick is better than you.”

Ryan replied, “Shut the [expletive] up” (which is kind of like saying “how ya doin’?” in New York, but I digress).

Ryan notably was fined $50,000 by the Jets last year after he flipped off a fan during a mixed martial arts event in Florida.

Belichick, the Patriots coach, reportedly uttered a profanity after the game, but the NFL says that was a private conversation, according to the Star-Ledger.
