Mariota (lower leg) participated in Saturday's practice, Cameron Wolfe of ESPN.com reports.
Mariota looked crisp throughout Saturday's session, according to Wolfe, connecting on several impressive throws to Delanie Walker and new target Eric Decker. After practice, Mariota told reporters that he fully trusts his surgically repaired fibula. Although the Titans will likely continue to be cautious with their franchise quarterback, it's encouraging nonetheless that Mariota looks no worse for wear early in camp.
