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

Some quick hits:

Cobb ready

The Titans excelled in the run game in the preseason opener, racking up 288 yards against the Chargers.

Running backs DeMarco Murray, Derrick Henry, Bishop Sankey and Antonio Andrews all had success.

Meanwhile, running back David Cobb was held out with hamstring tightness.

"I had a little bit of a setback, but I am feeling good now and excited to get out there for the first time this year and give it a run against a great defense,'' Cobb said. "I just have to stay focused and keep playing well.

"The room is very competitive, but the best thing is to stay healthy. Every guy in there is capable of going in there and giving great runs."

Cobb, a fifth-round pick by the Titans last season, knows he needs to perform well when given a chance on Saturday in preseason game No.2 vs. the Panthers. He was picking up momentum with some impressive practices before the setback.

"It is (important) for him, us,'' Mularkey said of Cobb. "He'll get options. He'll get in there early to get a good look at."

Smashmouth football**

Mularkey said the starters will play a little more than they did in the preseason opener, but a lot depends on drives and how the game unfolds.

Quarterback Marcus Mariota played three offensive series against the Chargers last week, but the first-team offensive line played longer.

The Titans expect a physical battle on both sides of the football.

"They like to be smashmouth, and so do we,'' linebacker Wesley Woodyard said. "Our rushing attack was good last week, and their rushing attack was, too. So it's going to be a battle of the run fits up front.

"But that's what you want in a football game. The fans are going to be excited about the head-butts going on."

Rivera praise**

Panthers coach Ron Rivera had plenty of nice things to say about the Titans leading up to Saturday's game. After watching tape of Tennessee's preseason game against the Chargers, Rivera came away impressed.

"When you watch what they're doing on tape, you see them spread people out, move people around, shift in motion, and then they're still running the ball," Rivera told reporters who cover the Panthers. "It is smashmouth, because there are a lot of inside runs, inside zone. You see some power plays, some counter plays, some gap-scheme stuff." 

Murray ran for 93 yards on six carries, including a 71-yard touchdown in the first quarter. Henry ran for 74 yards on only 10 carries, including a 6-yard touchdown run.

"They should (run it),'' Rivera said. "They've got the Heisman Trophy winner and DeMarco Murray back there. They've got a good combination of runners, and they can be a force most certainly to deal with."

**

Injuries**

Linebacker Aaron Wallace (ankle) was back on the practice field on Friday, and Mularkey called his quick return "amazing."

Wallace won't play on Saturday, and neither linebacker Kevin Dodd (foot). They'll go through pre-game warmups on Saturday, but Mularkey plans to hold them out.

Receiver Kendall Wright (hamstring) and cornerback Perrish Cox (ankle) are out for Saturday's game. Mularkey said the team is also considering holding out cornerback Jason McCourty, who is dealing with a hip flexor. Receiver Andrew Turzilli (groin, finger) is questionable.
