Chargers sign Whitehurst, release Volek

Charlie Whitehurst, who appeared briefly in two games during four previous seasons with the San Diego Chargers, is headed back to his former team.

The Chargers agreed to terms Friday on a two-year contract with Whitehurst and released fellow quarterback Billy Volek.

Whitehurst was selected by San Diego in the third round -- No. 81 overall -- of the 2006 NFL Draft but was traded to the Seattle Seahawks prior to the 2010 season.

He has only thrown passes for the Seahawks in his six-year career, completing 84-of-155 attempts for 805 yards and three touchdowns over two seasons. He had two rushing attempts as a third-stringer for the Chargers in 2006, gaining 13 yards with a TD.

Volek, a 12-year veteran, had backed up starter Philip Rivers. He spent five- plus seasons on the Chargers.
