Mirko "Cro Cop" Filipovic faces Roy Nelson at UFC 137 in Las Vegas in what could very well be the legend's last fight.
From Fedor Emelianenko to current No. 1 UFC heavyweight contender Junior Dos Santos, Cro Cop battled most of the top heavyweights competitors of the last decade.
After what seemed like a very possible retirement for the Croatian legend, Cro Cop is back for what could be his final fight.
Here are four reasons that his fight at UFC 137 could very well be his last chance at UFC glory.
If Cro Cop were to lose to Roy Nelson at UFC 137 it would be his third straight loss.
When was the last time the Croatian legend has had three straight losses? Never.
He did come close once after he suffered back-to-back losses to Gabriel Gonzaga and Cheick Kongo. In his next fight he faced Tatsuya Mizuno at Dream 1 and won by TKO in the first round.
Three losses would probably mean the end for Cro Cop. Would he be worth keeping around in the UFC following three losses?
Of course, UFC president, Dana White, can "Chuck Liddell" him into retirement after another loss for the legend.
If Cro Cop loses this fight by knockout, that will be his third straight loss by knockout and will be the fourth time in six fights he has been finished early.
Brendan Schaub and Frank Mir have both finished Cro Cop with a loss to Junior Dos Santos coming by submission due to punches.
In that fight with JDS, Cro Cop suffered a fractured orbital bone and even waved his hand at the ref and said "I can't see!"
Another knockout loss here could force Dana to pull the plug on Cro Cop's career.
Unfortunately no matter what sport you play and no matter how much of a legend you become, age always ends up creeping up on you and turning your career upside down.
It is just a fact of life. Cro Cop just turned 37 in September.
Of course you have the few fighters who fought past this age and fought well in their 40s (Dan Henderson and Randy Couture to name a couple).
But not everybody possesses that ability to take on opponents as well as age and Cro Cop seems to have lost a step from his Pride days.
That brings us here. On top of his age, Cro Cop just isn't Cro Cop anymore.
The Croatian we saw landing highlight reel head kicks isn't that man anymore. He may be a legend, but Cro Cop isn't that man anymore.
You could see flashes of it in both fights with Mir and Schaub, but not enough to say that he can return to his old form.
Nelson could very well end Cro Cop and could show once again that legend isn't getting back to his young self.
