Joe Rogan's live reaction to Sean Brady submitting Leon Edwards with a guillotine: "Oh my goodness!"

Joe Rogan was stunned as Sean Brady pulled off the most significant victory of his career so far. Stepping in as a replacement for Jack Della Maddalena, Brady traveled to London and shocked the world by submitting former UFC welterweight champion Leon Edwards with a mounted guillotine in the fourth round.

The fight started as a striking battle, but Brady dictated the terms with grappling exchanges in the second round. He controlled Edwards with top pressure and was always two steps ahead in the exchanges. The 32-year-old American kept landing strikes and constantly threatened with submissions.

As the fourth round began, Brady wasted no time securing another takedown, climbing to mount, and locking in the choke that forced an immediate tap.

Rogan was blown away by the magnitude of Brady's dominant win, considering that it came against a former UFC titleholder. As Brady sunk in the guillotine, Rogan said:

"He's going for the guillotine. Look at this, one-arm guillotine. Oh my goodness. Oh my goodness. Oh my goodness! He tapped, he tapped wow! Sean f*cking Brady... Holy sh*t! What a performance... Shut out against one of the best of all time in the division, former champion, beats his [Edwards] a*s and submits him."
