NASHVILLE, Tenn. — The Titans just wrapped up practice on Wednesday at Saint Thomas Sports Park.

On Sunday, the team will face the Chicago Bears at Soldier Field.

Three quick hits after today's practice:

Left tackle spot

Titans left tackle Taylor Lewan did not practice on Wednesday, but coach Mike Mularkey said he's improving.

"We're holding out hope he can play on Sunday," Mularkey said of Lewan. "He is better today than he was. Each day he has gotten better."

Dennis Kelly, meanwhile, worked with the starters at left tackle and is in line to start if Lewan doesn't play.

Kelly has played in 11 games this season, and he's stepped in for Lewan twice this season – once when Lewan was ejected early against the Packers, and then last week late when Lewan was injured against the Colts.

"I always prepare like I am the starter,'' Kelly said. "I'll be ready if I'm needed. I feel really good with this offense and really good with the offensive line. Hopefully I am not needed, but if I am I feel good."

Kelly, acquired via trade from the Eagles earlier this season, is from Chicago Heights, Illinois.

He grew up a fan of the Bears.

"It will be really exciting to play in Soldier Field,'' Kelly said. "I was a Bears fan, but when I got into football I really liked Jevon Kearse so consequently I was also a Titans fan."

CB update

On Monday, Mularkey said the Titans would discuss the possibility of making some changes in the secondary when asked about cornerback Perrish Cox.

Mularkey said Wednesday the team plans to stick with Cox, "but we're going to rotate much more than we have."

"I do have confidence (in Perrish),'' Mularkey said, "but we need to have other guys working as well."

Injuries

In addition to Lewan, running back DeMarco Murrray (foot), cornerback Brice McCain (knee) and tight end Phillip Supernaw (concussion) did not practice on Wednesday.

Mularkey said Supernaw remains in the concussion protocol.
