Its looks official. Cro Cop will more than likely face rising star Junior dos Santos.
The Brazilian striker is very inexperienced, has spent about a 1 minute inside the octagon and he's already facing Cro Cop. He trains with good people though, Nog and Anderson Silva. I've also seen him spare with Shogun Rua. According to his UFC biography he started training in 2005, I don't know how accurate that is but I wouldn't like to loose to a guy that took up the sport four years ago. Incidentally thats the same year Cro Cop faced Fedor.
One thing is for sure, the UFC loves Cro Cop. Eddie Sanchez, Gonzago, Kongo, Al Turk, now Dos Santos. Its another match-up that should suit the Croatian very well.
