Titans QB Jake Locker and WR Nate Washington were injured on the same play. Locker completed a pass to Washington across the middle and Washington was sandwiched between two defenders. He fumbled, and on the return Locker separated his non-throwing shoulder trying to make a tackle. Washington apparently injured his leg, though it looked like he took a blow to the head/neck.
Matt Hasselbeck would start for Locker if he can't go, though early reports indicate it's not too serious. Kenny Britt is due back next week, so Washington would compete with Kendall Wright to start on the opposite side.
