Another former Philadelphia Eagles offensive lineman is headed to the San Diego Chargers. The Chargers announced that they have signed veteran offensive lineman Tra Thomas to a one year contract. Thomas appeared in five NFC championship games, and on Super Bowl, for the Eagles. Last year, Thomas played for the Jacksonville Jaguars. Thomas follows Jon Runyan to play for the Chargers; Runyan played in San Diego for one year, and now is the republican nominee for a congressional seat in South Jersey.
