The Seahawks signed Fowler to a one-year contract Tuesday, Tom Pelissero of NFL Network reports.
The deal is worth up to $5 million. Fowler will turn 32 years old later this summer and is headed into his 12th season out of the University of Florida. He appeared in all 17 regular-season games with the Cowboys last season, making 11 starts, but recorded just 3.0 sacks as a sub-package edge rusher while playing 32 percent of the defensive snaps. In Seattle, he'll provide depth behind DeMarcus Lawrence, Uchenna Nwosu and Derick Hall.
