Philadelphia, PA – Chicago Bulls center Joakim Noah was out of the lineup Sunday for Game 4 against the 76ers because of a sprained left ankle.
Noah hurt the ankle in the third quarter of Friday's Game 3 loss when he stepped on the right foot of Sixers forward Andre Iguodala.
His absence leaves the Bulls without two of their top starters.
They were already missing star point guard Derrick Rose, who was lost for the rest of the season after suffering a torn ligament in his left knee in Game 1.
The top-seeded Bulls trail the best-of-seven series against Philadelphia, 2-1.
