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

On Sunday, the team will face the Denver Broncos at Nissan Stadium.

Three quick hits after today's practice:

Casey Update**

Titans defensive lineman Jurrell Casey did not practice again on Friday.

Casey suffered a sprained foot in the team's game against the Chicago Bears on November 27. He'll be listed as questionable for Sunday's game after missing practice all three days this week.

Casey didn't want to discuss the injury in the locker room on Friday.

"We held out Jurrell again,'' coach Mike Mularkey said.  "He'll be listed as questionable for the game."

Mularkey said the Titans have good depth behind Casey.

"(It all depends on) whether Jurrell can play or not,'' Mularkey said. "We are fortunate to have the depth that we do, but if he can play, he is going to play. We may keep an extra d-lineman up if that is the case, those are all things that are in discussions all the way up until 10:30 (Sunday) morning."

CB update**

Mularkey did not name a starter opposite cornerback Jason McCourty.

Veterans Brice McCain and Valentino Blake are in the mix, while LeShaun Sims will also be involved after playing against the Bears last week. The Titans promoted rookie cornerback Kalan Reed from the practice squad last week to replace Perrish Cox, who was released.

"We're still going to talk about it," Mularkey said. "We still have time. We have 48 hours to make the decision. We'll find out on Sunday."

McCain said the mindset remains the same for the group no matter who is in there, or who plays quarterback for the Broncos.

"We just have to make plays,'' McCain said. "The quarterback is going to give us plenty of chances, so make our plays. The team really relies on us. We have to keep the deep balls off us."

Other injuries

Defensive lineman Angelo Blackson was excused from Friday's practice with an illness, but he's expected to be available on Sunday.

Mularkey said tight end Phillip Supernaw (concussion) and safety Daimion Stafford (hamstring), who both missed the last game against the Bears, practiced all four days this week and have no issues.
