According to Jim Wyatt of the team's official website, head coach Mike Mularkey believes Mariota is right where he is supposed to be in terms of his timeline to return: "His status is good. His boot is off, he is walking around. You would not know he had an injury. There is no limp or gait in his walk. So he is right on schedule, if not ahead."
Mariota is expected to be ready for training camp in July.
While Mularkey didn't rule out the possibility that Mariota would take part in offseason work, he preached the importance of patience:
We're just going to listen to the doctors, listen to Marcus and see how he feels. We will allow him to do what he is capable of doing.
Marcus is working hard, and hopefully he'll be back sooner than later, I think that is what he wants to do. We are just going to wait and see ... and we have time. I am not going to push him.
If we have to adjust some things we do in practice to what he is capable of doing, we'll do that. As long as he is ready to go Week 1 that is all that matters to the team.

Mariota also rushed for 349 yards and two additional scores.
Perhaps most importantly, Mariota posted an 8-7 record as a starter after going just 3-9 during his rookie campaign.
The former Heisman Trophy winner figures to be among the biggest factors in whether Tennessee can continue to improve and reach the top of the winnable AFC South.
Until Mariota is able to return, the bulk of the work under center figures to go to veteran backup Matt Cassel.
Alex Tanney, who has 14 career NFL pass attempts, is also on the roster.
