"Detroit Lions running back Kevin Smith returned to practice today, while wide receiver Calvin Johnson continued to show progress.

Smith left Sunday's 17-10 loss to St. Louis with a shoulder injury and didn't practice Wednesday. He seems likely to play Sunday at Seattle, though coach Jim Schwartz isn't saying so.

"He's got a long way to go till Sunday, but I'm encouraged," Schwartz said today. "Kevin's a tough guy. Kevin's a hardworking guy. I know if he can go on Sunday, he'll go."

Johnson has missed two games with a right knee injury and was listed as limited Wednesday. He continued to look good in the portion of practice open to reporters, but Schwartz continued to say he would be a game-time decision.

"We're going to just be careful, do what I can do," Johnson said. "As long as I don't have any setbacks, I think it'll look brighter for Sunday.""
