New England Patriots kicker Stephen Gostkowski will undergo season-ending surgery for a left hip injury, a source told ESPN's Adam Schefter.

Gostkowski is expected to be ready for the start of the 2020 season, Schefter added.

The 14-year veteran has not missed a game since 2010 when a torn quadriceps muscle forced him to miss the final eight weeks. Shayne Graham kicked for the Patriots for the rest of that season as the only man not named Gostkowski or Adam Vinatieri to do so since 1995.

It was reported earlier Wednesday that the Patriots were working out several kickers at Gillette Stadium. Kai Forbath and Mike Nugent are apparently the two veterans battling to take over for Gostkowski, sources told Schefter.

Four-time Pro Bowler Gostkowski has struggled this season, missing four extra points through four games after misfiring on just three such kicks over the past two seasons. This year, he is 11-for-15 on extra points and 7-for-8 on field goals, with his lone miss coming from 48 yards.
