The team cited left knee soreness for Harper, and right ankle soreness for Fox. Each of them scored 24 points in the loss and almost turned it into a victory. Harper went down hard in the closing moments of Game 4 as he fought for a rebound with Minnesota's Ayo Dosunmu. He grabbed the offensive board, and Dosunmu wrapped him up and took him to the floor when he tried to go back up. Harper landed on his left knee, and Dosunmu landed on him and stayed there for a beat. Harper grabbed his knee, clearly in a good deal of pain before he hit the free throws.
