It was fine on Sunday when he played. It didn't start hurting until Wednesday and it hurt enough today that he asked me to drive him to see the Chiropractor. He just has to ice it for 15 minutes at a time to get the inflammation down and stay off of it if possible. Which is fine with me, I like being on top anyway... XD
He only plays basketball once a week, but he's had problems with his knees every January for the past few years. He has weak knee structures for his body. Ah well... it's just as well because Basketball-Buddy-P screwed up his ankle pretty badly and can't play for the next 2 months.
