MINNEAPOLIS -- Minnesota Vikings quarterback Tarvaris Jackson was carted off the field on Sunday with a concussion in the second quarter against the San Diego Chargers.

Jackson took off running on first-and-10 from the Minnesota 36 and scooted past the first-down marker. But as he was tackled, Jackson took a leg to the head. He remained on the turf with his hand up in the air in an awkward position, and several teammates took a knee in prayer nearby.

After a few minutes, Jackson sat up and was talking to team trainers before he was taken away. He rode on the cart to the tunnel to the locker room, then got up and walked into the room on his own power.

Jackson was on the sideline without pads on for the second half. Brooks Bollinger played in his place.

San Diego cornerback Quentin Jammer and defensive lineman Luis Castillo were also injured in the game. Jammer pulled a hamstring in the second quarter and was ruled out for the rest of the game, and Castillo injured his right leg in the third quarter and had to be helped off the field.

Coach Norv Turner said Castillo strained his knee and sprained his ankle on the play.

"I don't want to comment on how serious it is before they are able to do the tests they need to do, the MRI, but it looks like one that will keep him out a while," Turner said.

The Chargers already were without linebacker Shaun Phillips, a Pro Bowl alternate last season who missed the game with a groin injury.
