Noah got hurt midway through the third quarter of Friday night's loss at Philadelphia. He stepped on Andre Iguodala's foot driving the lane and crashed to the court. Noah instantly grabbed his left ankle in pain, though he returned to shoot free throws after a timeout. He also played briefly in the fourth quarter, before leaving the arena on crutches.
The eighth-seeded Sixers lead the series 2-1, winning both games after reigning Bulls star Derrick Rose tore a knee ligament and went down for the season.
