The Steelers signed linebacker Vic So'oto and running back Tauren Poole to reserve/future contracts Monday, giving them 23 such players under contract since the offseason began.

The 6-foot-3, 263-pound So'oto has played in 13 career NFL games with the Packers, Raiders and Cardinals. He also spent time with the Redskins and was on the practice squads of the Packers and Saints. He initially signed with Green Bay in 2011 as a non-drafted rookie from Brigham Young.

Poole (5-10, 210) spent time last season on the Colts' and Panthers' practice squads. A non-drafted rookie free agent from Tennessee, he originally signed with the Panthers in 2012, but missed that season with a rib injury.
