Both Buffalo Bills rookie linebacker Kelvin Sheppard and second-year receiver Marcus Easley will be out at least a week with injuries.
Sheppard strained his left hamstring on Sunday and watched Monday's practice from the sidelines. Easley is out with a hyperextended knee.
"Sheppard is going to be out for a little while," said coach Chan Gailey. "I think at least a week, and then we'll reevaluate at the end of the week." On Easley, Gailey said: "About the same thing. About a week."
Meanwhile, cornerback Domonic Cook, the rookie from the University at Buffalo, went down with a leg injury during the 7-on-7 drills. He limped off the field. Gailey said Cook "tweaked his knee" and would be further evaluated.
At inside linebacker, the Bills are using veterans Andra Davis and Reggie Torbor. Free-agent signee Nick Barnett will be able to start practicing on Thursday and should line up next to Davis. With Sheppard out, Arthur Moats and rookie Chris White worked with the second team at inside linebacker.
The Bills are deep at receiver but still want to get a good look at Easley, a fourth-round pick from 2010 who missed all last season.
"It's a big setback for him and it hurts our football team," Gailey said. "We'd like to know what he can do. We didn't get a real good look at him last year. Obviously we don't have a very good look at him now. But it's one of the things you go through. That's life in the league."
Veteran cornerback Reggie Corner came off the physically unable to perform list and was back at practice for the first time Monday. He is recovered from a sore ankle.
