Isaac drove the lane and did a hop step between two defenders against the Kings. He then immediately fell to the floor in pain, untouched, while clutching his left knee with 9:19 left in the fourth quarter during the Magic’s 132-116 win.
He was wheeled off the court accompanied by Magic president of basketball operations Jeff Weltman.
It was Isaac’s second game back since he hyperextended his left knee on Jan. 1 at Washington. Isaac, who missed 31 games because of the injury, left Sunday’s game with 4 points, 4 rebounds and 2 steals in 15 minutes.
