ESPN's Paul Kuharsky reported Mariota's presence in team drills, with backup quarterback Alex Tanney noting the team was pleasantly surprised by his return.
"Pretty cool to see him get out there," he told Kuharsky. "They didn't script it. Nobody expected it."
Titans head coach Mike Mularkey told Jason Wolf of the Tennessean last month he wasn't sure exactly how much Mariota would be able to do on the field during minicamp.
“We’re going to do some things that (Mariota is) going to be able to practice, do some things that aren’t going to subject him to (further injury),” he said. “We may do more 7-on-7s than we ever have done, just things like that to try to help him out.”
It was a disappointing end to a terrific 2016 for Mariota. The 2014 Heisman Trophy winner threw for 3,426 yards and 26 touchdowns in helping the Titans post their first winning season in five years.
