With international fight week headlined by two title fights, there is no bigger week for UFC. The end of the year show tends to have the best card, but nothing is bigger than the Fourth of July event. While the event has taken a hit from the Chael Sonnen saga, it remains to be an excellent card on paper. Chris Weidman returns to face Lyoto Machida in the main event. When two world-class fighters that have completely different styles face each other, the fight becomes even more compelling. Machida isnt receiving the publicity he deserves for how hes looked fighting at middleweight. Then Ronda Rousey makes another quick return to defend her title against Alexis Davis. It will be the first time that Rousey faces a black belt in Jiu-Jitsu. Stefan Struve makes his long awaited return against Matt Mitrione. It will be interesting to see how Struve bounces back from such a long layoff. Urijah Faber will be headlining the preliminary bouts against upstart Alex Caceres. The UFC has done an excellent job in building this card with well-known names. Here are ten things to watch for throughout UFC 175.
