The Las Vegas Raiders signed linebacker Jamin Davis to the active roster and placed right guard Jackson Powers-Johnson (ankle) on injured reserve on Tuesday.
Powers-Johnson, 22, got hurt in the second quarter of Thursday’s 10-7 road loss against the Denver Broncos.
A second-round pick in the 2024 NFL Draft out of Oregon, the 22-year-old Powers-Johnson started seven of eight games this season after making 14 starts in 15 games as a rookie.
The Raiders signed Davis, 26, to the practice squad on Oct. 8.

The Commanders released him on Oct. 22, 2024, then he briefly spent time on the Green Bay Packers and Minnesota Vikings’ practice squads. He played in four gamers for the Vikings and had four tackles and one sack.
