Oakland Raiders center Rodney Hudson emerged from Sunday's loss to the Pittsburgh Steelers with a sprained ankle, head coach Jack Del Rio announced.

A timeline for Hudson's return to the field remains unclear, as Del Rio indicated the team wouldn't know more about his status until later in the week.

Either way, the high-priced, free-agent addition appears to have avoided a more substantial injury.

Tony Bergstrom, who entered the game in Hudson's place down the stretch, would continue to see work with the first-team offensive line if he is forced to miss time.
