MLB Brian Urlacher was wearing a floppy hat, not a helmet for Wednesday's practice at Halas Hall, the first of two workouts scheduled for the bye week.
He was one of five players sitting out.
CB Nathan Vasher (groin) was sidelined as was RT Fred Miller, who has been battling a sprained ankle.
LG Ruben Brown and SLB Hunter Hillenmeyer were also out.
UPDATING: S Brandon McGowan, who banged up his right elbow in Philadelphia, also missed practice.
