The Walla Walla native had four catches for 42 yards in four games played. Martin didn't have a catch in last week's 30-20 victory over the Minnesota Vikings. In his place, rookie receiver Jermaine Kearse had one catch for 6 yards.
Martin was normally used as the backup slot receiver to Doug Baldwin.
Baldwin's return from a high ankle sprain last week meant less room available in the receiving corps for Martin.
The move also indicates that Braylon Edwards will be back later this week as the team's fifth receiver. Edwards has missed the last two games with a knee injury. He has eight receptions for 74 yards and a touchdown on the year.
The roster move leaves a spot open on the Seahawks' 53-man roster, with all indications pointing to cornerback Walter Thurmond being activated off of the Physically Unable to Perform list. A broken leg has sidelined Thurmond since last March.
