Israel Adesanya was left stunned after Alexander Volkanovski was brutally knocked out by Islam Makhachev at UFC 294. 

Makhachev defeated the Australian with a devastating head kick and punches in Round one of their highly-anticipated re-match.

It was an impressive performance from Makhachev and settled whatever debate still remained from the pair's first bout in February.

Incredibly, it was just the second time in Volkanovski has been stopped in his career and it came as a shock to training partner Adesanya. 

On his YouTube channel, FREESTYLBENDER, Adesanya posted his live reaction to the lightweight showdown. 

Once Volkanovski was kicked to the ground, Adesanya was silenced as he put his hands around his head in despair. 

He repeated 'F***' multiple times as he described what he had just seen. 

Adesanya attempted to keep a brave face and maintained his support for Volkanovski as he said: 'Still the best dude. I love this guy... f***'. 

'I felt strong,' an emotional Volkanovski said after his defeat. 'I felt strong in there, but obviously I've been telling you I want to put some hands on him and whatnot. 

'I wanted to pull the trigger, but it just felt a little weird in there, that little bit hesitant, which I didn't expect. It was like I was waiting for something. I was like, 'I'm going to go, I'm going to go,' and then he got me.' 

Meanwhile, Adesanya also reacted to Kamaru Usman's points defeat by Khamzat Chimaev, saying: 'It is what it is'.
