The announcement by Cro Cop ends speculation that he would rematch
"I must say I'm happy with this opportunity to fight again in this year. This wasn't the best year for me and I'm hoping that I'll end it in a good spirit," he continued.
"Although I'm still having some difficulties with my old injuries there won't be any excuses left in case of a bad result. I'll handle (these) issues in January, but against Choi, I'll be ready and nothing will stop me this time. I'll just do my best and end this year with a win hopefully. Then I'll focus on 2009 and work on the further steps in my career."
