Oakland Raiders will be without quarterback Derek Carr for two to six weeks after he injured his back in the 16-10 loss to the Denver Broncos.
Carr left the Raiders' game at Denver late in the third quarter on Sunday after being shaken up on a sack.
He was hit by defensive end Shelby Harris and was going down when defensive end Adam Gotsis flew in and wrapped a padded arm between his helmet and shoulder pads.
Carr remained on the ground for several moments as team trainers and medical personnel came on to the field to treat him.
He eventually was able to get up and walk off the field on his own power, holding his lower back.
Next up for the Raiders in the NFL is the visit of the Baltimore Ravens on Sunday.
