Giants running back Brandon Jacobs reportedly exchanged words with Jets coach Rex Ryan after the game's final whistle.
"Time to shut up, fat boy!" Jacobs yelled at Ryan, according to The Star-Ledger.
It didn't end there.
Jacobs told the New York Daily News that he instructed the Jets coach to "shut the (expletive) up," and Ryan reportedly told the running back to "go (expletive) himself)."
Jacobs also told The Star-Ledger that Ryan went after him on the field "the way his pops (Buddy Ryan) went after (Kevin) Gilbride."
When asked about the confrontation, Ryan said: "We had a private conversation. That's all I'll leave it as. He doesn't like me. I respect him, but I couldn't care less about him."
