This situation is personal for Izzy, he's not gonna move up to 205 and forget about DDP. He WANTS the fight. Khamzat sneaking in is a true possibility, but I presume the UFC will make every move possible and work every angle to make sure Izzy/Dricus is next. Everyone was talking after that rant in the cage, both Izzy and Dricus were all over the media that next week after. Interest in that fight is too high, and this the kind of watershed fight that gains them massive interest in Africa, a place in which the UFC would like a real footprint but has been unable to make happen, logistically.
Unless one of them dies, this fight is going down.
