The team said he could be suspicious to reunite with a stinger.
Backup quarterback Blaine Gabbert arrived the field to replace Mariota. Gabbert was the quarter back if the Titans came out after half time as well.
Mariota landed his knee since he was chased by Allen.
Mariota went down on one knee because he was coming off the field to speak with coach Mike Vrabel. The Titans’ training staff came onto the field and also talked matters over with Mariota until he walked off the field and headed straight to the tunnel.
The injury happened with 55 seconds left before half time. Tennessee was driving but settled for a 42-yard field goal by kicker Ryan Succop later Gabbert was terminated with a single second on the clock.
