(REUTERS) - Golden State Warriors' Kevin Durant has suffered a knee sprain and will be out indefinitely, the National Basketball Association (NBA) said on Wednesday, dealing a blow to the team's bid for a third straight trip to the finals.

Durant suffered the injury early in the Warriors 112-108 loss to the Washington Wizards on Tuesday when team-mate Zaza Pachulia fell backwards onto his left leg.

He was taken to a Washington area hospital where he underwent an MRI, which revealed Durant had suffered a Grade 2 medial collateral ligament (MCL) sprain and a tibial bone bruise.

The Warriors, who have the best record in the league at 50-10, said in a statement posted on the team's official Twitter feed that Durant will be re-evaluated in four weeks and could play again before the end of the regular season.

Durant, the 2014 NBA most valuable player, rocked the league last year when he left the Oklahoma City Thunder to join reigning MVP Stephen Curry to form a Dream Team in Oakland.

He leads the team in scoring (25.8 points per game), rebounding (8.4 rebounds per game) and blocks (1.7 blocks per game).
