Fitzpatrick's return was considered a long shot before this, but with five games remaining, this procedure makes it official. He suffered a hip subluxation in the second quarter of a season-opening loss to the Los Angeles Chargers and was placed on injured reserve.
Fitzpatrick, who underwent an MRI in early November, was still dealing with swelling and pain in the hip and groin area in recent weeks, preventing him from rehabbing.
Washington signed the 39-year-old to a one-year, $10 million deal in March, hoping his veteran savvy and steady play the previous few years would help. Fitzpatrick, who has played for nine franchises, had hoped to lead a team to the playoffs for the first time as a starter.
In 17 seasons, the former undrafted free agent from Harvard has started 147 games, throwing 223 touchdown passes and 169 interceptions.
His backup, Taylor Heinicke, has helped Washington (6-6) win four consecutive games to put it in position to make the playoffs. Heinicke ranks fifth in Total QBR over the past four games. For the season, he has thrown for 2,809 yards, with 18 touchdowns and 11 interceptions.
