Tennessee Titans quarterback Marcus Mariota is ailing again after suffering an elbow injury in the second quarter of Sunday's game against the Indianapolis Colts.
The Titans announced he was questionable to return, although a conservative approach could be expected after trailing 24-3 at halftime.
The quarterback was 10-of-13 for 85 yards and an interception before Blaine Gabbert replaced him.
Mariota missed four games as a rookie because of a Grade 2 MCL sprain, and his 2016 campaign came to a screeching halt in Week 16 when he suffered a fractured fibula.
