They really blew that out of proportion!
All week we've seen the commercials, focusing on Kristov's potentially TUF threatning injury, and what does it end up being? A slightly damaged thumb which they dedicate all of five seconds to on the actual show! Haha, I don't know about you, but I had to laugh. Here I was thinking, after seeing the adverts, that he had broken his hand and would probably be leaving the show as a result. Spike must have some wizards in the editing room, haha. That said, I'm happy Kristov is not in danger of being asked to leave due to injury. I've been looking forward to seeing him fight for some time.
