Mariota underwent an MRI on Monday, which revealed the sprain in his left knee. Wisenhunt also told reporters that Mariota's status for Week 7 is unknown, and that the quarterback “is walking around fine.”
Mariota sustained the injury in the first half of the Titans’ 38–10 loss to the Dolphins on Sunday, when he was hit in the left knee by defensive end Olivier Vernon. Mariota remained in the game and played with a brace.
Mariota, the second pick in this year’s draft, completed 21 of 33 passes for 219 yards with a touchdown and two interceptions in Sunday’s game. During his rookie season, Mariota has completed 64.1% of his passes for 1,020 yards, eight touchdowns and three interceptions.
