It's a bad injury. I have a friend who had a very similar injury. A specialist told him he couldn't do any athletic training for 12 weeks. He was advised to do some light raving and put on a 6-week course of Jagerbombs.
basketball players aren't exactly known for their toughness. they rate barely tougher than soccer pansies.
