Bulluck cracked cartilage in his ribs last week against Green Bay, jeopardizing his streak of 105 straight games at outside linebacker for Nashville.

"I don't know how many Tennessee Titans games you've seen in the last seven years where 53 wasn't out there," Bulluck said. "It's been mental all week, and it's going to be mental on Sunday, too. You know what I mean? Because I'll have to play through some pain, so I definitely have to get my mind right."

He said he doesn't believe he will make the injury any worse if he plays Sunday against the Chicago Bears.

Defensive end Vanden Bosch has battled a groin strain since Oct. 5.

"I think there was a slight tear originally," said Vanden Bosch, who hasn't finished any games since the injury. "But the rest has given it time to heal, so it should be fully functional. ... I've got confidence that it will feel good by Sunday, but I don't know what the decision will be."

Kick returner Chris Carr did practice Friday and was listed as questionable with a shoulder, as was linebacker Colin Allred with a groin injury. Defensive end William Hayes (illness) was probable.
