The defending champion Seattle Seahawks added a player to their summer roster Thursday while removing two players.

Wide receiver Morrell Presley signed with Seattle, which released tight end Chase Dixon and waived/injured guard Jared Smith.

Presley earned a job through a rookie tryout camp in mid-May. He finished his college career at California University of Pennsylvania after playing for UCLA.

Dixon, an undrafted rookie, signed with the Seahawks on May 10. Smith was a seventh-round draft pick in 2013, and he spent last season on the practice squad and on injured reserve due to a leg ailment.
