By now, fight fans are all too aware of the knee injury which Japanese featherweight icon Norifumi "KID" Yamamoto suffered in the lead-up to July's DREAM.5 show. The "pop" Yamamoto heard in his right leg after landing awkwardly during sparring for his eventually-scrapped bout with Californian Joseph Benavidez wound up being a torn ligament, which required immediate surgery and will most likely keep him on the shelf into 2009.

But Yamamoto updated his personal blog yesterday and revealed that he underwent another simultaneous operation which few, if any, were aware of - this one to repair a nagging left wrist injury sustained in training last September for a fight with Bibiano Fernandes. (Yamamoto fought with the injury and took an unsurprising unanimous decision.)

Oh, and he bought a NintendoDS:

I bought NINTENDO DS to kill my time. I play the role of a mayor in a game called "SimCity."

I didn't tell this before, but I had my left wrist operated on as well. I was injured my wrist during my training last September, a week before a fight with Bibiano Fernandes. I had kept training for my fight and I even had a fight without taking care of properly. I knew something was wrong. I couldn't throw powerful punches by my left hand because of the pain. Finally I had an operation to get rid of bones which don't stick together. I'm glad that I could have both my knee and wrist treated.
