Detroit, MI -- (Sports Network) - Detroit Lions offensive tackle George Foster, guard Stephen Peterman and running back Marcus Thomas are all listed as doubtful for Sunday's game against Chicago.

Foster started the first two games of this season for the Lions but has been nursing a knee injury since, missing practice all week. Peterman, a starting guard for the team the past two seasons, injured his hand and has also not practiced all week.

Thomas, who has not seen any action this year after serving as a return man in 2007, is nursing a hamstring injury.

Cornerback Leigh Bodden is questionable with a calf injury, and wide receiver Roy Williams is listed as probable after missing practice on Thursday.
