WATCH: Charles Oliveira and Beneil Dariush's inspiring connection caught on camera before epic battle

Charles Oliveira and Beneil Dariush are all set to go to war in the co-main event of UFC 289 at the Rogers Arena in Vancouver, British Columbia, Canada, this coming weekend. The No.1-ranked Brazilian contender will face the Iranian-American No.4-ranked UFC lightweight, in what could be a title-eliminator bout.

Given the scale of the bout, one wouldn't be remiss to think that either fighter wouldn't want to get close to each other before the event. However, given the nature of both Oliveira and Dariush, it came as no surprise when both lightweights shared a heartfelt moment a couple of days before competing for the possible title-contender spot.
