Ryan Fitzpatrick has retired, former Buffalo Bills team-mate Fred Jackson revealed on Thursday.

The 39-year-old quarterback played on nine teams in 17 seasons, although his 2021 campaign was ended by a Week 1 hip injury that ruled him out for the year.

Fitzpatrick had only signed a one-year deal with the Washington Commanders – then the Washington Football Team – and he will not return.

Jackson, a team-mate in Buffalo for four seasons, shared a text from Fitzpatrick, who said: "Forever grateful for the magical ride."

That message was posted on Twitter, with Jackson adding: "Congrats on a helluva career, Fitzy!! Loved sharing the field with you!! The gratitude is all mine!!"

Fitzpatrick finishes with 34,990 passing yards, ranking 32nd all time, although he never appeared in a single playoff game.
