Former Tennessee Titans kick returner Marc Mariani tried out for the San Diego Chargers this week, according to a league source.
Mariani is a former Pro Bowl selection in 2010 who has missed the past two seasons with shoulder and leg injuries.
He was in the final season of his rookie contract last season before injuring his shoulder.
Mariani had two touchdowns on returns as a rookie.
