(Nashville, TN)  --  Former Oregon quarterback Marcus Mariota may have one more game left in his rookie season.  Mariota tested his sprained right knee in practice, and the Titans are waiting to see how Mariota feels before deciding whether to play him in their season finale at Indianapolis.  The Heisman Trophy-winner has passed for over 28-hundred-yards with 19 touchdowns and 10 interceptions in his first season out of Oregon.
