The Seahawks released Harris on Tuesday, The Athletic's Michael-Shawn Dugar reports.
The move clears over $8.9 million in cap space for the Seahawks, as Harris was entering the final year of his contract. The 31-year-old was part of the return package from the Broncos in the Russell Wilson trade and started 15 games for Seattle last season, notching four forced fumbles and a pair of sacks. He's still an effective interior defender.
