QB Jake Locker (left shoulder) practiced for the second straight day Thursday, the Tennessean reports. Locker, who separated his left (non-throwing) shoulder in Week 2, remains on track to start on Sunday against the Chargers. To that end, he increased his reps in practice Thursday and threw well, according to coach Mike Munchak. "He probably did a little more than half the reps in each period, not quite everything but close," Munchak noted Thursday. "But he did well. He wasn't sore from yesterday, did more and hopefully tomorrow he'll do even better and on Sunday we'll just go play."
