Chargers WR Mike Williams departs with knee injury

Los Angeles Chargers wide receiver Mike Williams was carted off the sideline in the fourth quarter of Sunday's game against the Minnesota Vikings with a left knee injury.

Williams caught a pass over the middle when he took a hit from Minnesota's defensive tackle Harrison Phillips and grabbed for his knee. He was helped off the field before being taken to the locker room.

The Chargers' big-play threat had seven catches before his injury for 121 yards and a touchdown. He entered with 12 receptions for 128 yards over the first two games of the season.

Williams, 28, missed four games last season with a high ankle sprain.

In addition, Chargers safety Derwin James was ruled questionable to return with a left hamstring injury.
