Tennessee Titans quarterback Marcus Mariota will undergo an MRI on his hamstring after injuring it against the Houston Texans Sunday, head coach Mike Mularkey told Jim Wyatt of the team's website.
Mariota left the game and did not return after suffering the ailment on a touchdown run.
Titans backup Matt Cassel came on in relief and struggled, as Tennessee was blown out 57-14. If Mariota is sidelined for a significant amount of time, the Titans will likely face an uphill climb in trying to make the playoffs.
