Junior dos Santos is set to defend the UFC heavyweight title for the second time. If he is successful in doing so against former champion Cain Velasquez, Dos Santos will tie the record for most consecutive title defenses in divisional history.

In addition to the heavyweight title fight, UFC 155 will also feature some important bouts in the lightweight and middleweight divisions.

At 155 pounds, Jim Miller and Joe Lauzon will attempt to take a step closer to the first title shot of their careers. Also, on the preliminary card, Melvin Guillard and Jamie Varner will attempt to bounce back from losses.

Tim Boetsch will attempt to maintain his standing as an elite middleweight against the rising Costa Philippou. Additionally, Alan Belcher could break through with a win over longtime contender Yushin Okami.

Before Saturday's event, which will take place at the MGM Grand Garden Arena in Las Vegas, the fighters will hit the scales on Friday at 7 p.m. ET. Video of the weigh-ins will be streamed live on the above video player.
