ALLEN PARK, Mich. -- Detroit Lions coach Jim Schwartz says he's optimistic that wide receiver Calvin Johnson and running back Kevin Smith will play Sunday at Seattle.
Johnson has missed Detroit's past two games with a sore right knee but practised all week.
Smith, who injured a shoulder in last weekend's 17-10 loss to St. Louis, missed Wednesday's practice but took part in workouts Thursday and Friday.
Quarterback Matthew Stafford was limited in practice this week by a sore right knee but is expected to play against the Seahawks.
The last time Stafford, Johnson and Smith all played together was during the first half of the Lions' only win of the season, a 25-17 decision over the Washington Redskins on Oct. 26.
