The Raiders traded quarterback Kirk Cousins to the Vikings, leaving an open roster spot. They made up for it by signing rookie defensive lineman Tim Keenan to the 53-man roster from the practice squad.
Keenan was off the practice squad after the Raiders lifted him for the last three games.
In three games, Keenan totaled seven tackles and one sack while playing 35 percent of the snaps.
The Rams selected Keenan in the seventh round this year out of Alabama. They cut him from the preseason, but he returned to their practice squad.
The Raiders signed him to their practice squad on September 7.
The team also announced that it signed defensive tackle Chris Williams to the practice squad.
