Tennessee's backup plan has become reality.
Blaine Gabbert left the Titans' game against the Jaguars with an apparent injury after taking a hard hit while being sacked in the first quarter. After initial examination in the sideline medical tent, Gabbert was taken to the locker room where he's being evaluated for a concussion, according to the team.
Usual starter Marcus Mariota, initially left out of the lineup for a second straight week due to a lingering nerve injury, replaced Gabbert.
Around The NFL will have more on this story as information becomes available.
