The San Diego Chargers signed veteran free agents strong safety Corey Lynch, punter Robert Malone and offensive tackle Phil Trautwein following their first OTA on Tuesday. Lynch had 25 tackles and one INT last season for the Tampa Bay Buccaneers. Malone has five career punts in two seasons with the Detroit Lions. Trautwein has just one career start and his last regular-season game was in 2009 for the St. Louis Rams. The Chargers now have 90 players on their roster. Source: Dan McLellan, CBSSports.com
