Marcus Mariota limited in Thursday's Titans practice

QB Marcus Mariota loses some reps to backup Blaine Gabbert on Thursday as he continues to deal with elbow injury

Not so fast on the Tennessee Titans quarterback situation. Maybe. Possibly.

After declaring Wednesday that Marcus Mariota would start against Houston, barring any setbacks between now and Sunday, the Titans limited Mariotas reps Thursday in order to get backup Blaine Gabbert some work with the ones in practice.

He was about the same. We felt like we needed to probably get Blaine some reps as we evaluate the quarterback situation as we got closer to the end of the week, Titans coach Mike Vrabel said. So that was why he was limited, just because he didnt get the reps that he would normally get and just being able to evaluate which quarterback is going to be able to give us the best chance at the end of the week, especially on Sunday.

Asked if Mariota, who was knocked out of the season opener with an elbow injury, would still be his starting quarterback for the home opener against a division rival, Vrabel was still favoring that somewhat.

Right now it is, but that can change and well see where things go here when we get closer to game day, Vrabel said.

Elsewhere, the Titans top two draft picks were on the field together practicing fully for a first time since the first two days of training camp.

Second-round pick Harold Landry practice Thursday on his injured right ankle. He had done some limited work last week, but was inactive against the Dolphins.

Harold practiced today. He was a full participant. It was good to see him. Its good for me to kind of get those injured rehab guys on individual, Vrabel said. A lot of times those guys start to feel better than what they thought maybe just getting treatment or in a meeting. They get out, get on the field and do some things, so we always talk about, Lets worry about the things we can do, instead of the things we cant. They do the individual, and go, Well, lets go to the next drill and kind of see how it goes. He had a good day and was able to make it through practice.

First-round pick Rashaan Evans, bothered by a hamstring injury since the third day of camp, practiced fully for the second straight day for the Titans.

Left tackle Taylor Lewan was absent again as he remains in the leagues concussion protocol. Jack Conklin, who continues to work back from ACL surgery on his left knee in January, did not practice. Also tackle Dennis Kelly was absent with an illness.

Receiver Corey Davis was limited for the second straight practice with a hamstring, and was joined on the limited list by cornerback Kenneth Durden, also with a hamstring. Matt Dickerson and Derrick Morgan, both battling knee issues, were full participants Thursday.
