Interesting interview by Parisyan where he says that he challanged BJ Penn three times and he declined for some reason. He doesn't think that BJ was scared or anything, but it's interesting why BJ declined Karo 3 times, maybe he thinks karo is a bad matchup for him?

Good to see Karo taking his diet and training seriously for this fight, and the good thing is that he's not underestimating Diego and is taking it seriously. But the way he calls him "tough kid" you just get the feel that he'l really confident about this fight.
