The Seahawks have waived/injured defensive end Ryan Robinson, who sustained an Achilles tendon injury in OTAs.
Robinson spent time on the team's practice squad last season before signing a futures contract. He had been a pleasant surprise in OTAs this spring, even gaining some time with the first unit when Michael Bennett and Cliff Avril were unavailable.
If he clears waivers, he will be placed on Seattle's injured reserve list.
