Raiders starting guard Jackson Powers-Johnson is expected to be placed on the injured reserve list with an ankle injury he suffered in Thursday’s loss at Denver , according to a person with knowledge of the situation.

The second-year player could miss the rest of the season.

Powers-Johnson suffered the injury in the second quarter against the Broncos and did not return. Coach Pete Carroll said after the game the injury was significant.

“He hurt his ankle legit,” Carroll said. “I don’t want to go into any of the details of it, but … he’ll be out for a while.”
