Swaim (concussion) didn't practice Thursday, John Glennon of Sports Illustrated reports.
Swaim wasn't listed on the Titans' initial Week 11 injury report, so he likely suffered the concussion in Wednesday's practice. Friday's injury designation will help determine Swaim's chances of suiting up Sunday against the Texans, but his absence Thursday suggests he's in jeopardy of sitting out. If Swaim can't go, MyCole Pruitt and Anthony Firkser would take on larger roles at tight end for Tennessee.
