The Oakland Raiders roster continues to evolve after the draft, as the team announced they have signed three free agents after they tried out during last week’s rookie mini-camp.

The team announced they signed TE Paul Butler (California), FB Henry Poggi (Michigan) and RB Chris Warren (Texas).

Butler joins the team after participating in the Pittsburgh Steelers’ 2017 rookie minicamp. The 6-foot-6, 252-pound tight end played in 33 games over four seasons at Texas, hauling in 32 receptions for 381 yards and five touchdowns.

Poggi played four years at Michigan, making 13 starts at fullback and four starts at tight end. The 6-foot-2, 243-pound versatile weapon totaled nine career receptions for 68 yards and two career rushing attempts for six yards and one touchdown.

Warren played three years at Texas, carrying the ball 204 times for 1,150 yards and 13 touchdowns. The 6-foot-2, 246-pound running back also added 23 receptions for 242 yards and two touchdowns.

To make room for the additions, the Raiders released running back Elijah Hood, defensive lineman Joby Saint Fleur and fullback Nick Sharga.

Hood has since been picked up by the Carolina Panthers.
