Oakland Raiders sign three, waive three after rookie minicamp

The Oakland Raiders announced on Monday that they signed three free agents following their participation in the team's rookie minicamp on a tryout basis.

The three signed by the Raiders are tight end Paul Butler of California (Pa.), fullback Henry Poggi of Michigan and running back Chris Warren III of Texas.

The Raiders also waived three players: running back Elijah Hood, defensive lineman Joby Saint Fleur and fullback Nick Sharga.

Warren is the son of Chris Warren II, who played 11 NFL seasons and was named to three Pro Bowls.

The younger Warren had announced his decision to transfer from Texas before academic issues caused him to declare for the draft.

Butler totaled 32 receptions for 381 yards and five touchdowns in his college career, while Poggi made 13 starts at fullback and four starts at tight end, collecting nine career receptions for 68 yards.
