13. Nicco Montano (0 title defenses as flyweight champion)
[autotag]Nicco Montano[/autotag] was relatively unknown coming into Season 26 of “The Ultimate Fighter.”
As the No. 14 seed in a 16-woman bracket, Montano was able to upset Lauren Murphy, Montana De La Rosa, former Invicta FC flyweight champion Barb Honchack, and Roxanne Modafferi, en route to becoming the inaugural UFC flyweight champ.
However, she never ended up defending her title. The night before her scheduled fight against Valentina Shevchenko at UFC 228, Montano was transported to the hospital due to weight cutting issues and subsequently stripped of the title.
