Pittman served as the long snapper for the Houston Texans since 2003, before being suspended for four games last year after testing positive for a banned substance that is a violation of the NFL's steroids policy.
At 6-foot-3, 265 pounds, Pittman attended Thomas Jefferson High in Federal Way and played at the University of Washington.
Never miss a local story.
At 32 years old, Pittman is a younger replacement for 39-year-old Jeff Robinson, who came out of retirement to serve as the team's long snapper last season. Kicker Olindo Mara raved about the job Robinson did last season, saying Robinson was one of the reasons for the good season he had in 2008.
Seattle released 2008 sixth round draft choice Tyler Schmitt last month, and did not sign rookie free agent Sean Griffin out of Michigan.
Ryan Senser, a rookie free agent out of Ohio, remains on the roster and will provide some competition for Griffin. Although at 6-3, 241 pounds, Senser is smaller than Pittman and at 24 years old has less NFL experience.
