Kevin Durant needs more surgery, done for season

Reigning NBA most valuable player Kevin Durant needs another operation on his ailing right foot and will avoid basketball activities for four to six months, the Oklahoma City Thunder announced Friday.

That means Durant is officially out for the rest of the regular season and the playoffs, should the Thunder qualify. They head into Friday's action holding the eighth and final spot in the Western Conference.

Oklahoma City general manager Sam Presti said a week ago that Durant had been "removed from basketball activities" and could be shut down for the season. Presti made the decision official Friday when he announced that Durant will undergo bone graft surgery next week on his right foot.

Durant, 26, suffered a Jones fracture in the foot in October and missed the start of the regular season. He needed more surgery on Feb. 23 to deal with soreness caused by a screw inserted during the original procedure, but was hoping to return to the court.

Durant averaged 25.4 points, 6.6 rebounds and 4.1 assists in 27 games this season.

The four-time NBA scoring champion averaged a career-high 32.0 points last season en route to his first MVP award.
