Tennessee Titans quarterback Marcus Mariota may need to have a clean-up procedure on his right ankle during the offseason, according to NFL reporter Paul Kuharsky. Mariota had his right leg/ankle surgically repaired last season after breaking his fibula on Christmas Eve. The surgery required the insertion of a plate, and Mariota spent the offseason rehabilitating. In addition to his ankle issue, the hamstring that Mariota injured early in the season is still giving him trouble. The 24-year-old has struggled mightily in his third year, and it’s possible that the lingering health issues could be one of the primary reasons why. Mariota has thrown for 2,582 yards, 10 touchdowns and 14 interceptions while completing 62.2 percent of his passes and registering a passer rating of 76.9 thus far this season.
