ORCHARD PARK, N.Y. -- Buffalo Bills wide receiver Sammy Watkins suffered a hip injury in Sunday's 26-10 win against the Cleveland Browns.
It is unclear if Watkins, who played every snap in the contest, will be ready to practice Wednesday.
"I have no idea. I really don't," coach Doug Marrone said Monday. "I'll have a better gauge on it by Wednesday."
The rookie receiver has played through rib and groin injuries this season but has not missed a game.
Bills running back C.J. Spiller (collarbone), who is on injured reserve with a designation to return, is eligible to return to practice Wednesday.
"There's a bunch of paperwork and a bunch of rules," Marrone said. "I'll probably get them straight and if you see him out here, then I'll be able to tell you about the rules and things like that. But we have to file things."
