One day after signing with the Chargers, QB Kyle Boller left the team and apparently retired. Head coach Norv Turner told reporters after Saturday’s practice that Boller, "does not want to continue to play football," according to the San Diego Union-Tribune. A first-round pick by the Ravens in 2003, Boller played in two games with one start last season for the Raiders. The Chargers brought him in after backup QB Charlie Whitehurst suffered a sprained MCL in Thursday’s practice. San Diego will bring in another signalcaller since the only healthy QBs in camp as of Saturday evening were Philip Rivers and undrafted rookie Jarrett Lee. Source: Pro Football Weekly
