The UFC's experiment with a one fight deal did not go so well. Mirko Cro Cop has signed a three fight deal with DREAM and totally burned his bridge with the UFC. It's an unexpected move, as Cro Cop seemed genuine about his return to the Octagon. Before the fight, Dana White talked openly about how he never gives one fight deals and this is why. Cro Cop promised to sign on for two additional bouts after the fight, but for some reason had a change of heart (DREAM officials saw him win a fight on a UFC PPV and offered crazy money).
It's unfortunate because Cro Cop remains a very popular fighter. I think he's at the tail end of his career and wants to make the most money while he's still a draw. DREAM gives more upfront money, while the UFC gives you the chance to make huge money, as long as you win. Cro Cop took the easy money and financially it's probably his best option.
Still sucks for fans who wanted to see him matched up with the best the UFC has to offer.
