Kevin Durant has been ruled out for the remainder of the 2014-2015 NBA season, Oklahoma City Thunder general manager Sam Presti announced on Friday. The reigning MVP will undergo bone graft surgery on his right foot, and he will resume basketball activities in four-to-six months.

The six-time All-Star has played just 27 games this year, battling a foot injury. In October, he underwent surgery to repair a Jones fracture in his right foot, forcing him to miss the first month of the season. He last played on Feb. 19, undergoing another surgery four days later to get rid of the soreness he was feeling in that foot.

The second surgery wasn’t initially expected to keep Durant out beyond the playoffs, but Presti announced last week that the forward had been removed from all basketball activities. Durant, who entered the NBA in 2007, has had a relatively injury-free career prior to the start of the season.

The 26-year-old averaged 25.4 points, 6.6 rebounds and 4.1 assists in 27 games.

Oklahoma City holds the No.8 seed in the West with 10 games left to play. The Thunder are three games ahead of the Phoenix Suns, and are four games behind the No. 7-seeded Dallas Mavericks.

The 2015-2016 season will begin in late October or early November, meaning Durant should be fully recovered by preseason. Durant will be a free agent at the end of next season.
