Defensive backs Damarious Randall and Micah Hyde, along with starting center Corey Linsley, are listed as questionable on the Green Bay Packers' injury report for Thursday's game against Chicago.
Randall, a rookie, has played a key role in the secondary this season. He was limited in practice this week with a hamstring injury.
Hyde was also limited this week by a recurring hip injury that forced him to leave the 30-13 win over Minnesota on Sunday on a cart. But Hyde said this week that was only done as a precaution and the injury wasn't as serious as it looked.
Linsley left the Vikings game with a right ankle injury. He hasn't practiced all week.
The Packers have already ruled out receiver Ty Montgomery because of a lingering ankle injury.
