The Golden State Warriors couldn’t have foreseen this when they signed superstar Kevin Durant in the off-season.

According to The Vertical’s Adrian Wojnarowski, Durant suffered a hyper-extended left knee in a loss to Washington Tuesday night and his sources say that pending the results of a MRI, he could be done for the season — or longer.

Doctors have been reviewing the results and the team is expected to make an announcement later Wednesday.

Durant was injured when teammate Zaza Pachulia lost his balance and fell on his knee during the 112-108 defeat. The big center and four-time NBA scoring champ has been leading the Dubs in scoring this year with 25.3 points per game.

The Warriors signed him to a two-year deal last July and it was expected he was going to exercise a player option to become a free agent in July, with the stated purpose of signing a longer term pact.

Golden State currently has the best record in the NBA at 50-10 and losing Durant for the balance of the season — and possibly the playoffs — would be a severe blow. In other news, the team is set to sign Matt Barnes in the wake of Durant’s injury.

Update:

The Warriors have revealed the results of Durant’s MRI, and it’s just about the best news they could have hoped for.

In other words, no tears or structural damage that would require surgery. If all goes well, he could return before the playoffs start.
