Free agent WR Mike Sims-Walker is working out for the Titans on Tuesday. The Nashville Tennessean's John Glennon believes there's "no doubt" the move is related to Kenny Britt's recent "on- and off-field difficulties." MSW was unable to latch on with the veteran-receiver needy Texans earlier this summer despite two different tryouts, so it's doubtful he'll impress the Titans during his workout.
