Coach Mike Munchak said Monday he didn’t yet have enough information to determine the severity of guard Leroy Harris’ knee injury. Harris felt his knee give way during a play on the Titans’ first possession and was replaced by Kevin Matthews. Munchak said he didn’t think the injury was season-ending, but would know more after seeing Harris’ MRI results. Munchak expects starting left tackle Michael Roos (abdomen), cornerback Tommie Campbell (ankle) and linebacker Will Witherspoon (hamstring) to return to action this week, but remains uncertain about linebacker Patrick Bailey (ribs). Starting right tackle David Stewart suffered a slight hyperextension of his knee and might miss some practice time this week, but should be able to play Sunday. Source: The Tennessean
