The Tennessee Titans worked out veteran quarterback Kyle Boller on Tuesday, as well as veteran wide receiver Mike Sims-Walker, per TitanInsider.com.

The Titans open camp on Saturday, and currently the wide receiver position is a bit more unsettled than quarterback with Kenny Britt having both injury and off-field issues for the time being. First-round pick Kendall Wright is still unsigned as well, though a deal could still be completed before the first official practice on Saturday.

At quarterback, the Titans have Matt Hasselbeck and Jake Locker at the top with third-year pro Rusty Smith and undrafted rookie Nick Stephens on the roster as well.

Chances are, the Titans are simply looking around to see if either player fits a need, upgrades them in any way or could be part of an emergency list if an injury creeps up.
