Allen Park — The Lions were missing a couple starters in practice Thursday, but both are expected to play Sunday.
Left guard Rob Sims, who hasn't missed a start since 2009 when he was with the Seattle Seahawks, was out with an illness after being a full participant in Wednesday's practice.
Defensive tackle C.J. Mosley was also absent Thursday, but it was an excused absence. Mosley left practice early Wednesday because of the birth of his baby girl, so he's expected to play Sunday against the Chicago Bears.
Defensive tackle Nick Fairley was the only other player who missed practice, so the Lions remain a relatively healthy team heading into the final two weeks of the season.
Defensive end George Johnson, who missed practice Wednesday with an illness, returned. New cornerback Josh Thomas, whom the Lions claimed off waivers from the New York Jets Wednesday, was practicing and wearing No. 24.
Linebacker Ashlee Palmer (quad) and cornerback Mohammed Seisay (hamstring) were both limited. Wide receiver Calvin Johnson (ankle) and safety Don Carey (ankle) were full participants after being limited Wednesday.
