Tennessee Titans quarterback Marcus Mariota left Sunday's game against the Miami Dolphins with an elbow injury.
Mariota was replaced by Blaine Gabbert. Prior to leaving the contest, Mariota completed 9 of 16 passes for 103 yards and two interceptions, also rushing for 15 yards on three carries.
He appeared to suffer the injury after taking a hit from Dolphins defensive lineman William Hayes.
The quarterback wasn't the only key Titans player to suffer an injury, with left tackle Taylor Lewan ruled out after suffering a concussion and tight end Delanie Walker exiting with an apparent leg injury.
