Orchard Park, N.Y. — A week ago, the Buffalo Bills thought they had added one of the fastest players to ever enter the NFL when they claimed running back/return man Dri Archer off waivers from the New York Jets.

Then on Wednesday, the Bills placed Archer on the reserve/did not report list after he failed to show up to One Bills Drive. In an interview with Sports Illustrated, Rex Ryan said he isn't exactly sure why Archer didn't show up.

"I never even talked to the kid, so we'll see what happens," Ryan told Sports Illustrated. "He won't return a call. Is it him not wanting to be a Bill, or is it something else? I don't know, but I guess there's a reason Pittsburgh let him go (last November). But when you find something out, let us know, because I've never even talked to him."

That would leave the Bills with an open competition for the role of return man. Meanwhile, Archer is starting to run out of options in his NFL career.

The Bills have one open roster spot as long as Archer fails to report.
