QB Charlie Whitehurst will return to the Chargers with a two-year contract, according to a tweet by the team’s director of public relations. Whitehurst was San Diego’s third-round pick in 2006 and was a backup QB through 2009 until he was traded to Seattle . San Diego traded Whitehurst and its second-round pick (60th overall) in 2010 for Seattle’s second-round pick (40th overall) and a third-round pick in the 2011 draft.
