Titans expect QB Marcus Mariota to start Sunday

Barring any setbacks, QB Marcus Mariota should start Sunday for the Titans against the Texans

Marcus Mariota practiced fully on Wednesday, and is expected to make the start for the Tennessee Titans on Sunday against Houston barring any setbacks.

Mariota sustained an elbow on a hit from Miami's William Hayes while following through with a fake after a handoff in Sunday's loss. He attempted to stay in the game, but both passes thrown after the injury resulted in interceptions.

He's feeling good. He was able to practice. He had some rest there Monday and Tuesday, so he was able to get through and do everything and really be OK. I would say that barring any setbacks, Marcus is gonna be good to go on Sunday, Titans coach Mike Vrabel said.

Mariota said his arm felt OK after practice.

I'm feeling pretty good, kind of taking it one day at a time. But I was able to go through practice today and it felt pretty good, Mariota said.

Some of Mariota's throws during the open portion of practice seemed to lack the crispness and zip he normally throws with, but both Mariota and Vrabel felt that the quarterback's velocity on his throws was not an issue.

I didn't have the Jugs gun out, but for the most part, it looked like it was getting to where it was supposed to be, Vrabel said. I didn't notice a huge difference, but I didn't have the Jugs on him.

When asked about the speed on his throws, Mariota said he didn't notice any difference, but did say that the spin might have been altered due to the way the ball was coming out of his hand Wednesday.

I don't think velocity is a problem, the rotation of it maybe, Mariota said. But with that being said, as long as it gets there, it doesn't matter how it looks.

Mariota was listed as a full participant in Wednesday's practice.

The quarterback said he has never had this type of injury before, and admitted there was still a little bit of the tingling left in his throwing arm.

There are other concerns for the Titans as well. They have already lost tight end Delanie Walker to ankle surgery in what is likely a season-ending injury. He was place on injured reserve on Monday.

When you lose a guy like Delanie, who has been as productive as he has, it's a tough blow. So we'll definitely miss him, Mariota said.

Walker underwent surgery on his ankle on Wednesday Mariota had visited his star tight end in the hospital earlier in the week.

"I told him I was in that situation a couple of years ago an I told him he'll be back. He had no lack of confidence for sure," Mariota said, referring to his own fibula injury in 2016.

Also, left tackle Taylor Lewan did not practice on Wednesday as he is in the league's concussion protocol.

We haven't ruled him out, but he wasn't here today. We sent him home. He rested. He's trying to get back mentally right so we can evaluate him, Vrabel said of Lewan.

In addition, safety Kendrick Lewis (foot) and outside linebacker Harold Landry (ankle) were not on the practice field during the open portion of practice.

Among those limited on Wednesday were receiver Corey Davis (hamstring), defensive end Matt Dickerson (knee), linebacker Derrick Morgan (knee) and tackle Jack Conklin (knee).

Linebacker Rashaan Evans, the Titans' first-round pick, who has been out with a hamstring, was a full participant for the first time since suffering the injury.
