Mariani, 26, missed the entire 2012 season after breaking the tibula and fibula in his left leg and spent the entire 2013 season on Tennessee’s injured reserve after suffering a shoulder injury in training camp. Still, he flashed plenty of promise during his first two seasons with the club, returning two punts and one kick for touchdowns in 2010 and 2011. During his rookie season in ’10, he earned a Pro Bowl spot as a return specialist.
The Chargers hosted Mariani for a visit this week, but the Titans had always maintained interest in bringing him back. Still, it’s not clear what Mariani’s role on the 2014 roster will be, with return men Dexter McCluster and Leon Washington also under contract.
