Davis Unsure About Return

Results from an MRI exam on the swollen left knee of Terrell Davis showed no structural damage, but Denver’s star running back isn’t sure when he’ll be able to practice again.

Davis, who has had four knee surgeries in three years, had a cortisone shot on Monday to reduce the swelling and another injection to help ease an arthritic condition in his knee.

“They didn’t see anything that required surgery,” Davis said. “I was hoping it could have been a better situation if they had seen something and said this is it. There are a lot of different variables now. It is obviously not clear. We will see and go from there.”

Davis, who had surgery on his left knee twice in the last year, had been running hard and seemingly pain-free during camp but couldn’t play last week against Chicago.
