What's the worst sports related injury you've ever had?

[Schneed10]

Age 8 - Fractured Tibia (the big bone in your shin). Cast for 12 weeks.

Age 11 - Fractured Thumb (punched my friend in the head, he had a metal plate in his head and I just happened to hit it - sports related cause it's "boxing"). Cast for 3 weeks.

Age 15 - Knee cap grinding against cartilage. Got this one from pitching, plus I was growing like a weed and my bones were outgrowing my muscles. No cast or brace, just three weeks of physical therapy and I was good to go.

Age 18 - Spontaneous Pneumothorax (collapsed lung). This was scary, occurred while I was in the pool for swim practice at college. Trouble breathing and stuff. One week in the hospital for an emergency thoracotomy (removal of part of the lung). Three weeks of rest. Then I was back in the pool. Scariest injury for me by far, but quick recovery time when you consider the surgery.
