You can expect the Raiders to place him on injured reserve in the coming days and add someone to their roster.
Penn suffered the foot injury during the first quarter of Sunday’s loss to the Cowboys after he was rolled up on.
The Raiders had Marshall Newhouse move to left tackle with Penn out of the lineup.
Penn, 34, originally signed on with the Vikings as an undrafted free agent out of Utah State back in 2006. After a few months in Minnesota, Penn signed on with the Buccaneers during his rookie season and spent eight years in Tampa Bay before he was released back in 2014.
The Raiders signed Penn to a contract soon after before signing him to a $21M extension this past September.
In 2017, Penn appeared in 14 games for the Raiders and is rated by Pro Football Focus as the No. 23 offensive tackle out of 84 qualifying players.
