Barring anything unexpected he is set to play:

He "looked lively," per Scott Brooks, and beat writer Anthony Slater would be surprised if Durant didn't return for OKC's next game on Wednesday against the Suns. Durant's owners have to be happy with the news, and it looks like the reigning MVP will be ready to return mid-week barring any unforeseen setbacks. Perry Jones will head back to the bench.
