(Dave Mandel/Sherdog)UFC Fight Night 66: Who’s on the Hot Seat? RJ Gardner May 14, 2015 Events, Previews, Spotlight For a fighter, making it to the UFC is the culmination of years of hard work and dedication; countless hours of blood, sweat and tears being poured on to training mats. But once they make it to the UFC, the hard work doesn’t stop; in fact things get more difficult for the fighters. The UFC by nature breeds a competitive atmosphere, but that atmosphere is amplified by the fact that fighters are given only a handful of opportunities to prove they belong. Lose your UFC debut and you are lucky to get a second chance. Lose back-to-back bouts and your back is against the wall. And fighters who lose three straight are almost always guaranteed their release from the organization. When the UFC heads to the Mall of Asia Arena in Pasay City, Philippines, for UFC Fight Night: Edgar vs. Faber, seven fighters will be fighting for their jobs. Loser of Jon Delos Reyes vs. Roldan Sangcha-an The UFC flyweight division is as thin as they come, but even so, if fighters want to stay in the UFC, they need to win fights. Sangcha-an and Reyes are a combined 0-3 in the UFC Octagon. The loser of this bout will surely not be asked back any time soon. Loser of Nolan Ticman vs. Zhikui Yao Ticman and Yao both young fighters with plenty of potential, but both came up short in their UFC debuts. This will prove to be a pivotal bout in both fighters’ careers as the loser will likely be sent back down to hone their skills and compete with smaller organizations. Kajan Johnson Johnson is an experience vet who can potentially add a lot more depth to the lightweight division. He’s not a fighter that will ever be in the UFC title mix, but his exciting go for broke style is endearing to the fans. But at the end of the day, he needs to win to stay in the UFC after getting knocked out in his UFC debut last year. Phillipe Nover It’s been a long time since TUF 8 runner-up Nover was last seen in the Octagon. After an impressive showing on his season of TUF, Nover lost to Efrain Escudero in the finale and then went on to lose two more fights before being released. Since that time, he has gone 5-2 and is currently riding a three fight win streak. But as good as he has looked as of late, he cannot afford to come up short on Saturday. Luke Barnatt Following his time on season 17 of TUF, Barnatt’s UFC got off to a great start as he went 3-0 in the Octagon with two wins by stoppage. But since that time, Barnatt has dropped back-to-back split decisions and now his back is against the wall.
