The Seattle Seahawks released tight end Michael Palmer on Tuesday. With the vacant roster spot, Seattle signed defensive tackle Martin Parker.
Parker initially signed as an undrafted rookie free agent with the New York Giants on July 28, 2011. He spent the Giants Super Bowl-winning 2011 season on injured reserve. Parker did not play in a game last season and was released by New York on February 6.
Palmer signed with Seattle on July 23. The Seahawks now have seven tight ends on the 90-man roster, and eight players capable of playing defensive tackle.
