"Tokyo’s Yoshida, who remained on the canvas while being tended to by commission doctors, was removed from the Octagon on a stretcher as a precautionary measure. He was later treated and released from a local hospital for a concussion."

-- Ultimate Fighting Championship (UFC) today provided a medical update on Yoshiyuki Yoshida via its Web site. "Zenko" was brutally knocked unconscious last night during his main event welterweight tilt against Josh Koscheck at UFC Fight Night 16: "Fight for the Troops" and was wheeled out of the Octagon on a stretcher as a precautionary measure. It was the first time ever the super tough Japanese standout was put to sleep. It was also the first time ever Koscheck scored such a decisive finish. Unfortunately, the result was the culmination of a night of carnage -- Corey Hill (leg), Razak Al-Hussan (elbow/arm), Brandon Wolff (head) and Jonathan Goulet (head/knee) all sustained rather serious injuries. Get well soon.
