"Lions coach Jim Schwartz said Friday he's "optimistic" that both receiver Calvin Johnson and running back Kevin Smith will play Sunday at Seattle.

"As long as everything keeps going the way it is the next few days, I'll be all right," Johnson said after practicing again Friday.

Johnson has missed the last two games with a right knee injury, while Smith suffered a shoulder injury last week against St. Louis. Smith said Thursday he expected to be ready to play against the Seahawks, as will quarterback Matthew Stafford, who returned from a three-week absence to play against the Rams last week."
