Collins was added to the injury report and did not practice Thursday due to an elbow injury. Coach Lovie Smith didn’t get into the specifics of Collins’ injury but didn’t sound optimistic.
“When you miss practice on a Thursday, it’s not a good thing," Smith said.
If Collins can’t play Sunday, Oniel Cousins likely would get the start.
Defensive tackle Clinton McDonald (hamstring), tight end Brandon Myers (calf), running back Bobby Rainey (ankle) and tight end Austin Seferian-Jenkins (back) also were held out of practice. Middle linebacker Mason Foster was excused from practice for personal reasons.
