NASHVILLE, Tenn. – Titans quarterback Marcus Mariota was injured late in the first half of Saturday's game vs. the Redskins, and he did not return.
Back-up quarterback Blaine Gabbert stepped in for Mariota, and guided the Titans to a 25-16 win.
The Titans announced Mariota's injury as a stinger.
Coach Mike Vrabel said after the game Mariota "is still being evaluated."
Mariota was injured after being sacked on a first-and-10 play from the Redskins 14. Trainers examined Mariota on the field, and he headed to the locker room prior to the half. Mariota remained in the locker room during the second half of the contest.
"I think the conversation (with him) was, "How are you doing?," Vrabel said of Mariota. "I have been out there on the field, and you never want to leave (the game) – that's why you play. You feel for every guy that goes down, whether that be Jurrell (Casey) or Marcus. Any time you walk out there you hope that they'll be OK … that they can physically be fine and finish the game and help us.
"It was just unfortunate, like a lot of injuries."
Vrabel was asked if Mariota dealt with arm numbness like he did earlier this season.
"I think they'll let us know where we're at," Vrabel said of the team's medical staff as it relates to Mariota. "When he does (talk to media), he'll be able to talk to you about what he felt, and I'll talk to the doctors here in a little bit."
Mariota completed 10-of-13 passes for 110 yards before leaving the contest.
Gabbert said Mariota congratulated him after the contest.
The Titans wrap up the regular season next Sunday against the Colts, and Mariota's status for that contest likely won't be determined until later next week.
"He was happy (about the win)," Gabbert said of Mariota. "I just told him I always have his back. He works so hard for this football team, and we have a lot of fun together in the quarterback room. Anything I can do to help him succeed – and I know he feels the same way – I am willing to do."
