The Tennessee Titans are healthy for the season opener, but they did get a couple of scares this week in practice, including Pro Bowl tackle Taylor Lewan going down with a twisted ankle. Head coach Mike Mularkey said Lewan is “day to day” and is still expected to play Sunday against the Oakland Raiders. Cornerback LeShaun Sims also got dinged this week when he strained a groin muscle in practice Monday. Mularkey said Sims is also “day to day” and is also expected to play. Rookie wide receiver Corey Davis continues to do more and more in practice as he recovers from a pulled hamstring.
