Titans CB LeShaun Sims uncertain to play against Raiders after tweaking groin

NASHVILLE, Tenn. -- The Tennessee Titans' secondary has a tough challenge against the Oakland Raiders' talented receiver core Sunday and it could be more difficult if they're without one of their top cornerbacks in LeShaun Sims.

Sims didn't practice Wednesday, after tweaking his groin Monday during a special teams drill. Titans head coach Mike Mularkey listed Sims and left tackle Taylor Lewan, who was limited in Wednesday's practice with a sprained ankle, as day-to-day.

Thursday will be the big day, Sims said, to determine whether he would be able to play Sunday. Sims is hopeful, but the last thing he wants is for the injury to linger.

"I feel like it's getting there. I've got to give it time to get back where it usually is," Sims said Wednesday. "You don't want to try to come back too early and do something to put yourself out longer than it would have been. I'm just trying to put this behind me and get back on the field."

Sims spent the early portions of practice rehabbing inside on a rope pull machine. He said he's done a little jogging, but no actual football drills since suffering the injury. He said running full speed will be the barometer on whether he will play Sunday.

"I haven't tried to move a lot," Sims said. "I tried to do a little something, opening up a little and trying to sprint, pulling on it."

The Titans signed Logan Ryan this offseason to be their top cornerback. Sims, rookie Adoree' Jackson and veteran Brice McCain have been competing for the starting spot opposite Ryan all summer with Sims typically manning the role. Jackson would likely be the starter if Sims can't go on Sunday.
