This weekend's UFC 145 will feature a clash between top light heavyweights and former teammates Jon Jones and Rashad Evans. The elite 205-pound fighters have been butting heads ever since Jones accepted a title fight as a replacement for an injured Evans, but they may finally settle their differences on Saturday.

The fight card will also feature the return of Rory MacDonald, a young Canadian fighter touted by many as the next Georges St-Pierre. MacDonald will meet a fellow rising star in Che Mills, who picked up a dominant victory over Chris Cope in his UFC debut.

Contenders Brendan Schaub, Mark Hominick, Miguel Torres, Michael McDonald, Travis Browne and plenty of other talented fighters also fill out a night of fights that should be one to remember for quite some time.

Before Saturday's event, the fighters will hit the scales at the Philips Arena in Atlanta, Ga. on Friday at 4 p.m. ET. Video of the weigh-ins will be streamed live on the above video player.
