Matt Hasselbeck (calf) did not participate in Titans practice Wednesday. Hasselbeck's injury has been deemed "mild," but coach Mike Munchak says he's still in "wait and see" mode with his starting quarterback. The Titans continue to leave the door ajar for No. 8 overall pick Jake Locker to make his first career start against the Colts, and if Hasselbeck's "mild" injury holds him out again Thursday, Locker could be in the driver's seat.
