I could see the issue with that too. The word back in April of 2024 was that he was getting his knee scoped, which is a rather non-invasive kind of knee surgery. Now the Courier Journal is saying he had a hole in his cartilage and had a second surgery in July of 2024, which didn't clear him until January of 2025. It's fine if that's the case, but the timelines should have been spelled out better when it happened. I don't doubt that is what Khalifa is banking on.
Secondly, the academic ineligibility aspect of his initial year could keep him out, even if it was the covid year.
