UFC star Colby Covington made a streamer vomit after having no mercy on him in the octagon.

Australian streamer Chrogman, just 19, has made a name for himself on the platform Twitch by offering out, and fighting, his followers in various locations across the globe. 

His streams have seen him throw punches in front of the Eiffel Tower, square off against KSI's brother Deji in London and he's even been offered out by the controversial Andrew Tate. 

But this time Chrogman took it too far. 

The young Aussie agreed to enter into welterweight UFC star Colby Covington's world with a bout in the octagon - and it didn't end well for him at all. 

The video, posted on Covington's YouTube channel, began with the professional sportsman outlining exactly what Chrogman's challenge for the day was. 

'My boy Chrogman came through, we're going to get some training and I got a special gift if he's able to beat me in training today,' the 37-year-old explained. 

'If you're able to beat me in training today, I've got $30,000 for you bro. If not, you got to go in the cold tub.'

After a brief warmup, it was time for the novice and the experienced pro to face off in the octagon.  

The one-time UFC champion gave Chrogman plenty of opportunity to land some punches as the fight began before launching his own attack.

With the 19-year-old pinned against the cage, Covington started to blister him with body shots leaving him on the floor in a heap.

The streamer did however get back to his feet, warning those around him: 'I might throw up in the octagon, is that alright with everyone?'

However it wasn't long before Covington left the young man groaning on the floor in pain once again and, this time, he did indeed throw up all over the octagon floor. 

'It's not a good idea to challenge a UFC fighter, who's also a champion, to any sort of boxing fight,' Chrogman admitted. 

Covington was nevertheless full of praise for his opponent and the bravery he showed to agree to the fight. 

'He's a bright young mind and he's f*****g got a ton of talent,' he said. 

'You're 19 years old, I'm 37. I've been world champion, so I'm double your age, I've got so much experience. 

'The more experience he gets, just train smarter, not harder, that's the most important key to combat sports and just have fun with it. Thanks for coming and being the man in the arena.' 

Success in the UFC has however been few and far between for Covington in recent years. 

After beating Jorge Masvidal in Nevada back in 2022, the California-born fighter has competed just twice and has failed to win on either occasion. 

He most recently took Joaquin Buckley at UFC Tampa last December, losing via third-round knockout.
