ALLEN PARK — Quarterback Matthew Stafford’s big test will be to see how his injured right knee reacts on Wednesday following Tuesday’s practice. If there’s no swelling or irritation and he can continue to practice, obviously it will be a good sign. Although he said it’s way too early to predict whether he’ll be able to play on Sunday against the winless St. Louis Rams.

Stafford said he felt good during Tuesday’s practice, his first since Oct. 14. He was limited, taking about half the reps.

“This is the most I’ve done on it other than that Wednesday (Oct. 14) and it felt better than it did that Wednesday. I don’t know if I could say how much better or how close I was to 100 percent,’’ Stafford said. “This is the first time I’ve really tested it. I’ve just been walking around.’’

The rookie quarterback injured his right knee in the loss at Chicago on Oct. 4 and missed the two games since then.

Coming off a bye week, the Lions (1-5) had an unusual Tuesday practice. They are preparing to play the St. Louis Rams (0-7) on Sunday at Ford Field.
