The Raiders signed free agent tight end Paul Butler on Thursday.
Butler spent most of the previous two years on the Raiders’ practice squad, but was picked up late last season by the Detroit Lions as a reserve/future free agent. Butler (6 feet 6 inches, 250 pounds) also was promoted to the Raiders’ active roster in Week 17 of the 2018 season.
Butler has not played in a regular-season game.
To create room, the Raiders placed tight end Nick O’Leary on the reserve/nonfootball injury list.
