Chargers' Pro Bowl center Nick Hardwick is expected to be out three to four weeks with a sprained right foot. The prognosis was the best Hardwick could hope for, and since the Chargers have their bye this Sunday, that means he'll probably miss two or three games. "It's good news," said Hardwick, who was on crutches. Hardwick was hurt early in Sunday's 28-14 win over Oakland -- when LaDainian Tomlinson rushed for 198 yards and four touchdowns -- and expected the worst. An MRI on Monday confirmed the initial diagnosis of a sprain.
