LAKE FOREST, Ill. -- Chicago Bears cornerback Charles Tillman was held out of practice Wednesday as he deals with a groin issue that cropped up late in Sunday night's victory over the Pittsburgh Steelers.
In addition, cornerback Sherrick McManis was also held out of practice with a quadriceps injury.
Bears coach Marc Trestman categorized both players as "day to day" after practice Wednesday.
The 32-year-old Tillman has already dealt with a number of issues during the first three weeks of the season. During the first two weeks he was playing with a knee injury, while also missing time during the Sept. 8 season opener because of dehydration.
Trestman deduced that the groin issue was probably the result of overcompensating for the knee problem.
Tillman did not play late in Sunday's game as a precaution, and the injury is not deemed to be serious and he could play Sunday at Detroit.
"We moved some people around today," Trestman said about his defense. "C.J. [Wilson] got some work today, obviously. And Zach [Minter] will continue to work over there [on the defensive line] as well."
