Former SeattleSeahawks QB Charlie Whitehurst has agreed to a two-year deal to return to San Diego, the team announced on Friday. Seattle traded for Whitehurst in 2010 to compete with QB Matt Hasselbeck, but Whitehurst struggled to make a major play for the job, throwing just three touchdowns in two years. Whitehurst appeared in nine games and made four starts for Seattle included a season-ending victory over the St. Louis Rams in 2010 to give the Seahawks the NFC West title.
