This happened repeatedly in his fight with Cheick Kongo in the UFC and just recently, with his fight against Alistair Overeem at DREAM.6. I just hope Cro Cop has had all the kids he wants.

Although bloodied, Cro Cop wanted to fight on, but ringside doctors thought otehrwise, as this post from from bloodyelbow.com says:
Cro Cop Wanted to Fight On: "I Knew My Time Would Come"

"Alaister was ahead on points, however its a 15 minute fight and i knew my time would come" said Mirko.

Mirko wanted to continue to fight, however the ringside doctor prevented him from continuing.

"I'm angry it ended this way, it seemed as if he was the dominant one, however i wasn't in trouble for a second and was waiting for my opportunities. I prepared very well because I thought the match could last a while. I thought i would knock him down in the end."

His manager Zvonimir Lučić confirmed that he wanted to continue the fight however the ringside officials prevented it as a precaution.

His manager stated that the injury is not a serious one. He doesn't know when the rematch will take place however Mirko's team want one as soon as possible.

It is thought that Dream could host an event in Korea, before the NYE event.
