Durant is dealing with a left ankle sprain and has been ruled out for Sunday's game against the Nets, Chris Haynes of ESPN reports.
If the Warriors fall behind in Brooklyn on Sunday, they won't have the luxury of relying on Durant.
A team source told SFGate.com he believes Durant suffered the injury in the first quarter of Golden State's victory in Philadelphia.
The Warriors travel to Oklahoma City to play the Thunder on Wednesday night. He scored 27 points on 11-of-20 shooting with five rebounds and two blocks in 33 minutes.
After that hard-earned win, Durant gave his game-worn KD 10 sneakers to a lucky young fan. The reigning Finals MVP is having yet another strong season, averaging 24.9 points, 7.0 rebounds, 4.9 assists, and a career-high 2.2 blocks. The last game Durant missed Andre Iguodala got the start, while Patrick McCaw and Omri Casspi saw more minutes off the bench.

He had also chose to "personally cover the costs of victims' funerals and burials, and the care of the injured", it said. Distributions of food aid are common in the North African nation, notably in remote parts of the country.
