MMA is an intense sport. Accidents happen. During a training session for my next fight I dislocated my knee. On a kneeblock takedown my leg bent inward and the kneecap went outward. When I saw this I turned away with a wince and it popped back into place. As of now I do not need surgery but only a couple of months of rehabilitation. Good thing I am training with Michael Jocson. I am already back in the gym and can't wait to start kicking some butt again }:-)
