ALLEN PARK, Mich. -- Detroit Lions wide receiver Calvin Johnson returned to practice Thursday, albeit on what appeared to be a limited basis, and after he was done, he said his injured knee feels "good."
He wouldn't go near whether he'll play Sunday.
"I'm feeling better," Johnson said. "I'll just leave it at that."
That isn't atypical for Johnson, who routinely declines to discuss injuries. When asked if his knee was sound enough to play against the Cleveland Browns, he responded with "Come on, man."
Johnson missed the fifth game of his career Sunday, a 22-9 road loss to the Green Bay Packers. He attempted to test the knee before the game and afterward said he was close but couldn't end up making the call to play.
He didn't want to go into specifics, either, about what in his workouts tells him whether he'll be able to play on game days when he is dealing with injuries.
"Just knowing my body, I know what I can do," Johnson said. "I know what I can do. I know where I'm at."
Lions coach Jim Schwartz has said this week that the team will likely wait until Sunday to make a decision on its star receiver. He cautioned not to read too much into Johnson practicing Thursday and going through positional drills.
"You guys saw what you saw," Schwartz said. "But, you know, just like before, he's working hard to get better every day, and let's see where we get to when we get to Sunday."
Johnson isn't the Lions' only pass-catcher who may not play Sunday. Tight end Tony Scheffler is dealing with a concussion, the third of his career. Schwartz said Thursday that Scheffler's concussion symptoms did not appear until two days after the game against Green Bay.
