Then he took a medical timeout and a bit later, they recorded him talking to Toni where he said something along the lines of "I've got torn ligaments for sure!". Then he said that he is in the QF of the AO and would never retire... which is kinda funny I thought because the year before he retired in the QF.
The thought of 4 straight majors must have been driving him.
