Watch: Mark Zuckerberg's wife Priscilla Chan looks away in shock as Raoni Barcelos gets taken down by Trevin Jones at UFC Vegas 61

Mark Zuckerberg and his wife Priscilla Chan were in attendance at UFC Vegas 61. The closed-door event was headlined by a women's strawweight clash between Mackenzie Dern and Yan Xiaonan.

The co-founder and CEO of Meta Platforms took to Instagram to post a picture of himself and his wife along with Dern backstage.

While Zuckerberg thoroughly enjoyed the fights, which were evident from his reactions, Chan had a hard time dealing with the violence. Bantamweight fighters Raoni Barcelos and Trevin Jones battled it out for three rounds in a high-paced fight on the main card.

During the final round of the fight, Barcelos pressured Jones against the octagon with a barrage of punches. The American, however, secured a body lock in an attempt to slow down Barcelos. After Barcelos attempted a spinning elbow, Jones ducked down to secure a takedown.

The sequence drew quite a reaction from Priscilla Chan, who was caught on camera looking away in shock.
