The auction description notes that the ring is in "virtually pristine condition" and has an estimated value of at least $100,000. Gordon's name appears on one side of the ring, while the other side features the final score of Super Bowl LIII and the words "Still Here."
Bidding on the ring opens Aug. 7.
Gordon spent a season and a half in New England after arriving via trade from the Cleveland Browns in September 2018, catching 60 passes for 1,007 yards and four touchdowns in 17 games.
The 29-year-old was suspended indefinitely in December for violating the NFL's policies on performance-enhancing drugs and substance abuse. He reportedly applied for reinstatement last month.
