The Seahawks added two players to the roster Monday from the rookies who tried out for the team this weekend — tight end Rashaun Allen and guard Nate Isles — and signed fourth-round pick Cassius Marsh to his rookie contract.

Seattle cut tight end Travis Beckum and cornerback Jimmy Legree to make room for Allen and Isles on the 90-man roster.

Allen, a 6-foot-4, 250-pound tight end from Southern University, was impressive throughout the three days of the rookie minicamp. Isles, a 6-5, 348-pounder from North Carolina A&T, played guard and tackle at the minicamp. The team lists him as a guard.

Marsh, the 108th overall pick in the draft, could be due a $470,252 signing bonus and the standard four-year deal worth $2.69 million, according to

Unlimited Digital Access. $1 for 4 weeks.

Marsh is the fourth of the team’s nine draft picks to sign, the others being fifth-round DT Jimmy Staten, sixth-round DB Eric Pinkins and seventh-round FB Kiero Small. The other five draftees are expected to be signed before camp begins.
