Mariota (knee) was a full participant at Wednesday's practice, but his hamstring injury from earlier this season is still having an impact, and his fibula fracture from last year may require a clean-up procedure at the end of the campaign, according to Paul Kuharsky of PaulKuharsky.com.
Mariota finds himself on the injury report ahead of the Titans' Week 15 game in San Francisco with a minor injury in the same left knee that he has worn a brace on ever since suffering the second MCL injury of his playing career in 2015 (the first occurred in 2013, while he was still in college). Though it doesn't seem that any of these lingering leg injuries pose a threat to his availability, they might help to explain why Mariota has taken a clear step back in his third professional season. If he does end up having surgery on his leg or ankle, it probably won't have a major impact on his offseason preparation, assuming he's able to go under the knife shortly after the season. The Titans enter Week 15 positioned for a playoff spot, but their recent form doesn't exactly hint at a deep run.
