The Facts: Marcus Mariota is reportedly dealing with a sprained left knee, but the injury is not considered serious at this time.
Diehards Line:Mariota suffered the injury in Sunday's game against the Cardinals, but did not miss a snap because of it. He is expected to practice on Wednesday and barring any setbacks, he should play in Week 15 against the 49ers. If he give it a go, he can be considered a high-end No. 2 QB with upside.
