Low-Ki has been close to retiring for a while now, but apparently the final straw was an injury he suffered in the All Japan wrestling promotion. Low-Ki suffered a flak injury during his first New Japan tour. The injury came in a match with Akebono and original rumors indicated that it was either broken or crushed ribs. Akebono weighs over 500 pounds and Low-Ki weights about 175.
He went to Twitter and said he was retiring, partially based on All Japan refusing to honor their contractual obligations for medical care after he was injured wrestling for them. This makes sense in a way.
Low-Ki has wrestled exclusively for the indies since he failed to make a mark in the WWE as Kaval. He charges a large sum of money to wrestle in the indies, but even that money is not enough to cover the medical care for crushed ribs. With Low-Ki wanting to move on with a movie career, especially with voice over work, risking his livelihood on wrestling for an indie seems a risk he is no longer willing to make.
Low-Ki was the very first ever Ring of Honor world champion back in 2002 and also debuted with the new TNA Wrestling as part of the Triple X faction that terrorized the company. He was part of some of the biggest X-Division and tag team matches in the early days of TNA.
He was one of the hottest indie stars and got a chance to make it in the WWE in the second season of NXT, which he won. Low-Ki wrestled on “Smackdown” for a short time, but was never pushed and after he accidentally gave Dolph Ziggler a concussion, he was released in a few months.
