DENVER -- Las Vegas Raiders starting right guard Jackson Powers-Johnson was ruled out of Thursday night's 10-7 loss to the Denver Broncos after suffering an ankle injury, and coach Pete Carroll said he will be out "for a while."
Powers-Johnson was hurt at the beginning of the second quarter when he rolled his ankle while quarterback Geno Smith was sacked by Denver edge rusher Nik Bonitto.
Powers-Johnson was on the ground momentarily and then helped off the field by trainers. The Raiders took down the medical tent and carted Powers-Johnson into the locker room.
The former Oregon standout was not the only injury on Las Vegas' offensive line. Starting left guard Dylan Parham suffered a high ankle sprain, also in the second quarter.
The injuries left Las Vegas without three of its starters on the offensive line. Veteran left tackle Kolton Miller is on injured reserve because of an ankle injury.
Smith, who was sacked six times, was limping late in the game and had his left quad wrapped at the end. Carroll said Smith sustained a bruise to his thigh but that he isn't expected to miss any time.
