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

On Sunday, the team will face the Chicago Bears in preseason game No.3.

Three quick hits from today:

Austin Johnson progress

Titans coach Mike Mularkey raved about the progress of defensive lineman Austin Johnson earlier this week.

On Friday, Johnson said he feels much more comfortable heading into his second NFL season, and it's paying off.

"I just feel a whole lot better about the defense, and how to play it,'' Johnson said. "And I'm more comfortable in the games from the experience I've had. I feel better about the technique, and playing at a consistent pace."

Johnson started at defensive end in Saturday's game against the Panthers. He has two tackles in two preseason games.

As a rookie, Johnson recorded 15 tackles, a half sack and a tackle for a loss in 10 games.

Johnson has worked both at end and inside on the team's defensive line.

"He's playing fast, he's playing physical,'' Mularkey said of Johnson. "He's holding the point very well. The violence in his game is getting better, it has since he's been here. I've been pleased with the way that he's played."

Murray a question mark

Mularkey on Friday wasn't willing to declare running back DeMarco Murray a go for Sunday's game. While he's been encouraged by his recovery coming back from a hamstring injury, he's still monitoring practice tape.

Murray hasn't played in the first two preseason games.

"I'll make that decision after I watch the tape today," Mularkey said of Murray. "I felt (he'd play against the Panthers) this time last week and game-time, I made a decision. I want to watch the tape on DeMarco."

Injuries

Add receiver Harry Douglas to the list of players who won't play on Sunday.

Mularkey said Douglas is dealing with a knee injury.

Receivers Eric Decker, Corey Davis and Mekale McKay also won't play against the Bears after missing practice again on Friday.

Defensive back Curtis Riley also missed practice again, and won't play. Safety Da'Norris Searcy was excused from practice again Friday for personal reasons, but he's expected to play.

Fullback Jalston Fowler and linebacker Nate Palmer returned to practice, along with nose tackle Antwaun Woods, who left practice early on Thursday because of a strained hip muscle. Mularkey said those players will be game-time decisions.

Mularkey said he's liked what he's seen this week from receiver Tajae Sharpe, who is expected to make his 2017 preseason debut on Sunday. Defensive lineman Karl Klug is off the injury report and ready to go as well.
