HENDERSON, Nev. -- Las Vegas Raiders starting right guard Jackson Powers-Johnson will be placed on injured reserve due to an ankle injury, coach Pete Carroll said Monday.
Powers-Johnson will miss at least four games, but a source told ESPN that the injury could sideline him for the remainder of the season. He is not expected to have surgery, the source said.
Powers-Johnson was injured in the second quarter of Thursday night's 10-7 loss to the Denver Broncos. The second-year lineman rolled his ankle while Denver edge rusher Nik Bonitto sacked Raiders quarterback Geno Smith.
The former Oregon standout was helped off the field and eventually carted into the locker room. Carroll said postgame that he expected Powers-Johnson to be out "for a while."
With Powers-Johnson sidelined, the Raiders will be without at least two starters on the offensive line when they play the Dallas Cowboys next week on "Monday Night Football."
Starting left tackle Kolton Miller has been on the injured reserve since Oct. 2 due to a high ankle sprain and a hairline fracture, which he suffered in Week 4's loss to the Chicago Bears.
Starting left guard Dylan Parham suffered a high ankle sprain against Denver. Carroll had said Parham attempted to reenter the game but was held back.
