The Chicago Bears signed running back Senorise Perry and safety Marcus Trice after they tried out at a rookie minicamp.
Perry was a two-year starter at Louisville, rushing for 677 yards and six touchdowns last season.
Trice is an Oklahoma transfer who finished his career at North Texas.
He was named first-team all-Conference USA after leading his team with five interceptions. He also blocked two punts and one field goal.
They cut punter Drew Butler and running back Willie Carter.
