It's very rare that a fighter just has one fight in the UFC, once that fighter has made it there. The usual standard for a fighter losing their debut, is that they get at least one more fight to redeem themselves. If they don't, they are usually released after going 0 - 2. Here though, are some one and done UFC fighters. Not counting any fighters one and done before 2001 (Zuffa purchase) - so no Kazushi Sakuraba when he fought at UFC Ultimate Japan in 1997 (...twice in fact due to a referee error - the early days were a lot different). Maiquel Falcao 1 - 0 in the UFC. Defeated Gerald Harris at UFC 123. Neil Wain 0 - 1 in the UFC. Lost to Shane Carwin at UFC 89. James Zikic 0 - 1 in the UFC. Lost to Phillip Miller at UFC 38. Neil Grove 0 - 1 in the UFC. Lost to Mike Ciesnolevicz at UFC 95. Dmitriy Sosnovskiy 1 - 0 in the UFC. Defeated Mark Godbeer at UFC FN 127. Jimmy Flick 1 - 0 in the UFC. Defeated Cody Durden at UFC FN 183. James Tony 0 - 1 in the UFC. Lost to Randy Couture at UFC 118. Am I missing any?
