Orchard Park, N.Y. — Not only is Buffalo Bills coach Rex Ryan planning on attending Donald Trump's rally in Buffalo, but he's going to be introducing Trump to the crowd at First Niagara Center.

Rex Ryan addresses the media during an NFL football news conference where he was introduced as the new head coach of the Buffalo Bills, Wednesday, Jan. 14, 2015, in Orchard Park, N.Y.

"Well, I don't know we'll have to stick around and find out," Ryan said when asked about it Monday. "Yeah, it should be interesting."

So does Trump have Ryan's endorsement for the Republican nomination for president?

"Oh my gosh," Ryan said. "I'm going to introduce him, that's true. That's a true statement. But I'm not going to say who my endorsement is and all that stuff. I'll say this, Chris Christie was my guy 100-percent because we were the lap-banded brothers. We both had that lap band and we really are pretty close."

He may not be publicly endorsing Trump, but introducing him at his rally certainly has a similar effect.
