KUSA- There's an unwritten code among NFL players that Terrance Knight believes Tyrann Mathieu of the Arizona Cardinals violated. Sunday night during the San Antonio Spurs blowout victory over the Miami Heat, Mathieu Tweeted "This is turning out to be worse than the super bowl."

"I don't take any nonsense especially from other players. Him being in the fraternity of playing football should have known better," Knighton said Monday.

Knighton took to Twitter and responded 17 minutes later "Don't worry. Y'all on the schedule."

"I took it personal and I knew the risk of writing back" Knighton said after practice. "Like I said they're on the schedule and we have a heck of an offense and we'll see what he tweets after that."

The Broncos and Cardinals play Sunday, October 5 at Sports Authority Field at Mile High.
