#4 Mizuto Hirota
Despite having just one loss in his last six fights, Hirota is certainly vulnerable heading into his lightweight matchup against Ross Pearson. The Japanese fighter was pulled close to 24-hours before UFC Fight Night 117 featherweight matchup against Charles Rosa due to a failed weight cut.
As we all know missing weight is one of the cardinal sins of being a fighter and combine that with a unanimous decision loss to Alexander Volkanovski in his last fight, it's a recipe for disaster. The 36-year-old moves back up to the 155-division for the first time since 2012 and has only competed twice since 2016.
