The Titans placed Haskins (undisclosed) on injured reserve Monday, Jim Wyatt of the team's official site reports.
Haskins had been dealing with an undisclosed injury, but now that he's on IR, Tyjae Spears profiles as the Titans' top backup behind lead back Derrick Henry to start the coming season. Also in the team's depth mix are Julius Chestnut and Jacques Patrick, but it's possible that further moves could be made to fortify Tennessee's backfield ahead of Week 1.
