Stephen Curry will undergo an MRI on Saturday to determine the severity of his MCL sprain.
JaVale McGee fell on the left leg of Curry during Friday's game. Curry immediately began hoping and limping in pain.
"I was just trying to block a shot and I ran into him," McGee said.
Curry told ESPN in comical fashion, "I'm good. Well, at least it's not my ankle."
"We'll see what the MRI says tomorrow," Steve Kerr said. "There's not a lot we can do or predict. Kind of a strange, cruel twist of fate, you know. He rehabs his ankle for the last couple of weeks, gets that strong, and then the knee goes. So we'll see what happens. Keep our fingers crossed."
Durant suffered a sprained MCL late last season but was able to recover in time for the start of the playoffs. Curry's MCL injury occurred later in the season.
