Rex Ryan: Staying on own side in pregame warmups is 'unwritten thing'

ORCHARD PARK, N.Y. -- Buffalo Bills defensive backs Nickell Robey-Coleman and Stephon Gilmore made headlines Wednesday when they said they would retaliate Sunday if a New England Patriots player ran through their pregame warm-ups.

Rex Ryan said Wednesday there is "zero focus" on "extracurricular things" like the pregame scuffle that erupted Oct. 2 when Bills players felt "disrespected" by quarterback Jacoby Brissett running through defensive backs' warm-ups and Bills safety Robert Blanton began a shoving match.

However, Ryan suggested Thursday that Brissett might have crossed a line that day.

"It's no big deal. It's kind of an unwritten thing in the NFL," Ryan said. "So whatever happens, it's no big deal. Focus is on just playing the game."

Asked to clarify the "unwritten" rule, Ryan said, "I mean, you got your spot on the field where you're supposed to be, and that's just the way it is. It's always been that way for the 20 years I've been in the league and much longer than that.

"But trust me, it's no big deal. I've never thought one second of it. It's about the game, and that's all that matters."

Defensive coordinator Dennis Thurman addressed the topic for the first time Thursday.

"That stuff happens," he said. "It really has no effect on the game, at all. We're not looking for anything like that. You don't anticipate anything like that happening. So we'll get ready to play Sunday, 1 o'clock. Whenever kickoff is, we'll be ready to go."
