Seahawks sign seven to practice squad, including WRs Kevin Smith and Kasen Williams

The Seahawks have signed the following seven players to their practice squad, the team announced Sunday.

RaShaun Allen, TE: He spent last year bouncing back and forth between the Seahawks' active roster and practice squad. Allen (6-4, 250) originally was signed by the Seahawks as an undrafted free agent. He had one catch for 13 yards in the preseason.

Will Pericak, G/C: He started his career as a defensive tackle with the Baltimore Ravens, but has been trying to transition to the offensive side of the ball in Seattle. Pericak (6-3, 300) has bounced around to five teams (the Ravens, Jaguars, Chargers, Broncos and Seahawks) since entering the league in 2013.

Eric Pinkins, LB: The Seahawks selected him in the sixth round of the 2014 draft as a defensive back. Pinkins (6-3, 230) spent his rookie season on the reserve/non-football injury list (foot). This offseason, he's made the transition to linebacker. Pinkins started and was active in the preseason finale against the Raiders.

Terry Poole, OL: A fourth-round pick in the 2015 draft, Poole (6-5, 323) didn't show enough this summer to earn a roster spot on the 53-man squad. But the organization obviously believes in his potential and will continue to try to develop him.

Kevin Smith, WR: He was released after training camp by the Seahawks for the second straight season, but will stay in the building this year. Smith (6-0, 218) had six catches for 61 yards during the preseason.

Rod Smith, RB: An undrafted free agent out of Ohio State, Smith (6-3, 231) carried 10 times for 70 yards during the preseason.

Kasen Williams, WR: He participated in the team's rookie camp and was signed in June. Williams (6-1, 219) had four catches for 58 yards and a touchdown during the preseason.

Teams can have 10 players on their practice squads, so expect the Seahawks to make three more additions.
