Hall is the career FCS leader in tackles for loss with 86.5. He will be a teammate with the previous record holder, linebacker James Cowser, who also plays for the Raiders. Cowser had 80 tackles for loss with Southern Utah.
Hall also had 42 sacks and nine forced fumbles during his career at Sam Houston State. His 14 blocked kicks with the Bearkats likely means the Raiders will also use Hall on their special teams unit.
Oakland's sixth-round pick Azeem Victor signed his rookie deal Saturday, leaving the Raiders with seven unsigned picks.
