Joe Rogan was left stunned after Sean Strickland dropped Israel Adesanya during their UFC 293 clash.
On Sunday morning, Strickland caused a huge upset in Sydney, Australia after he managed to outscore the heavily backed Adesanya.
As the fight was happening, Rogan hosted a watch-along on YouTube as he opted against making the trip to Australia.
Rogan’s reaction to Strickland scoring a heavy knockdown in the first round has since gone viral.
The 56-year-old was seen smoking a cigar as the move happened, leading to him continuously shouting ‘Oh my God’.
Strickland followed up the knockdown with a series of ground strikes.
Eventually, Adesanya fell to a shock unanimous defeat to Strickland.
After watching the event, Rogan said: “I’m stunned. I think this is the most stunned I’ve ever been, surprised at a performance.
“Like, Holly Holm-Ronda [Rousey]. I knew Holly was dangerous. I knew Holly was a legit striker and if Ronda couldn’t get her to the ground, Holly is a multiple-time world kickboxing champion.”
He continued: “When he cracked him with that right hand in the first round, I was like, ‘What world? What timeline are we on?’”
Whilst Strickland said during his post-fight interview: “Am I dreaming, am I going to wake up? Somebody hit me. Never in a million years did I think I would be here. I don't cry much but I'm trying to keep [myself] together right now.
“Izzy's had how many highlight knockouts, he's beaten the majority of my friends pretty easily. I was even doubting myself at times, but the fans in Australia motivated me.”
He added: “I give so many brain cells to the MMA gods every day. I thought I'd be walking away a little bloody and broken up, I'm still shocked that didn't happen, this is the first time I'm lost for words.
“But remember, this gold around my waist doesn't mean [anything]. What matters is how you live your life, and I'm living better through you guys, for you guys, thank you.”
