Golden State Warriors star Kevin Durant has a mild right calf strain and will miss the rest of the Western Conference semifinals against the Houston Rockets, league sources told ESPN’s Adrian Wojnarowski on Thursday.

Durant will be re-evaluated next week, a source told Wojnarowski. The Warriors lead the best-of-seven series 3-2, with Game 6 on Friday (ESPN, 9 p.m. ET). If Golden State can’t close out the series then, Game 7 will be Sunday (ABC, 3:30 p.m. ET).

The injury occured with 2:11 left in the third quarter of Game 5 on Wednesday night as Durant went up for a jumper over Rockets swingman Iman Shumpert. Durant did not appear to make contact with Shumpert, but after landing, he took a few steps up the court, then clutched his right leg. He limped toward the Rockets’ bench, and after a few moments, he went straight to the Warriors’ locker room, accompanied by trainers and general manager Bob Myers.

Durant had an MRI on Thursday.

Warriors coach Steve Kerr and guard Stephen Curry noted that Durant was understandably down after the injury, but there was a palpable sense of relief within the locker room that his injury wasn’t more severe. Initially, players and coaches feared that Durant tore his Achilles tendon, but Kerr was told by the Warriors’ medical staff that that was not the case.
