UFC 191 takes place in in Las Vegas and features a flyweight title fight between Demetrious "Mighty Mouse" Johnson and John "The Magician" Dodson, a rematch of their fantastic 2013 title match. Dodson is seen by many as the only fighter who has a realistic shot at dethroning Mighty Mouse, and he hasn't lost since that 2013 meeting. Also on the card, a pair of heavyweight legends meet when former UFC heavyweight champion Andrei "The Pitbull" Arlovski meets Frank Mir in the co-main event of the evening. Both men are experiencing the most unlikely of career resurgences in their mid-30s: Arlovski has not lost since rejoining the UFC last year, and has won three straight in the promotion, while Mir, after suffering through an unbearable four-fight losing streak that saw many calling for him to retire, has bounced back and knocked out both Antonio "Bigfoot" Silva and Todd Duffee in 2015. One of these men may be fighting for a title in 2016, while the other will see his comeback stalled, but no matter who wins, expect fireworks. Other fighters of note include Anthony "Rumble" Johnson taking on Jimi Manuwa at light heavyweight, and UFC breakout strawweight star Paige VanZant returning to take on Alex Chambers. Who wins? Who loses? Lets take a look at five main card predictions for UFC 191!
