Patriots star receiver Julian Edelman, who helped New England win three championships and was the MVP of Super Bowl LIII, announced his retirement in a video posted on social media Monday.

The NFL transaction wire released Monday stated that Edelman had his contract terminated by the Patriots, but the roster move is expected to be a technicality as part of his retirement, a source told ESPN.

Edelman, who turns 35 next month, was limited to six games last season because of a chronic knee injury. He spent his entire 12-year career with the Patriots and ranks second in NFL history with 118 postseason receptions, behind only Jerry Rice’s 151.

Edelman caps his career in second place on the all-time Patriots chart for receptions (620), behind only Wes Welker (672). He is fourth on the team’s career receiving yards list with 6,822 receiving yards, behind only Stanley Morgan (10,352), Rob Gronkowski (7,861) and Welker (7,459).
