WR Johnson misses practice with knee injury

ALLEN PARK, Mich. -- Detroit Lions wide receiver Calvin Johnson missed practice Wednesday with an apparent knee injury according to the Lions official practice report.

He was one of four starters to miss practice Wednesday. Wide receiver Nate Burleson (forearm) is not expected back for some time. Safety Louis Delmas (knee) shouldn't be a concern as he also missed last Wednesday's practice. Starting left guard Rob Sims (shoulder) also was held out of practice but worked on the side with trainers.

Defensive end Ziggy Ansah (abdomen) and linebacker DeAndre Levy (abdomen) being limited in practice were among two of the newer names on the report. Joining them as limited were linebacker Ashlee Palmer (ankle), safety Don Carey (hamstring), tackle Jason Fox (groin) and wide receiver Patrick Edwards (ankle).

Edwards said Wednesday he is on his way to getting better and participated in the individual drills portion of practice.

"High ankles take longer to heal and it's really slow as far as range of motion in my foot," Edwards said. "My lower foot and my lower ankle, it's good. The high ankle part, some kind of membrane part, like, it takes slow to heal."

During the drills, he said he felt good during portions of it, but cutting is still an issue.

"I was feeling good on the ladders," Edwards said. "As far as cutting-wise, it's a little ginger on it. It's getting better. I feel like I'm on track to come back, try to come back as fast as I can."
