Marshall’s playing time this season had diminished greatly, with the 34-year-old veteran getting just two offensive snaps in Sunday’s 28-14 win over the Detroit Lions. He had no targets in the game and was targeted only twice in the past three games.
He signed a one-year deal with the Seahawks before this season, and he caught just 11 passes for 136 yards and one touchdown.
Marshall is a six-time Pro Bowl selection who has six seasons with at least 100 receptions — the most by any player in NFL history. He was released by the New York Giants in April after just one season, and he has yet to appear in an NFL playoff game during a career that spans 13 seasons.
He has also played for the Denver Broncos, Miami Dolphins, Chicago Bears and New York Jets. He has 970 catches for 12,381 yards and 83 touchdown grabs. He is 16th in receptions — only 12 behind Hall of Famer Randy Moss.
