Johnny Walker is notorious for his post-fight celebrations. However, maybe he should avoid using the worm next time.Walker earned yet another first-round stoppage victory at UFC 235, and in the process became the sixth fighter in UFC history to start his career with three first-round stoppages after an incredible KO over Misha Cirkunov with a flying knee.But the emphatic victory came at a cost too, as the Brazilian's perfect night at the office was to take a U-turn after the fight was put to a stop.The 26-year-old saluted the crowd before falling directly forward with his arms by his side.As the Brazilian approached the mat, he put both arms out in front of him to cushion the blow, but as he attempted 'The Worm', Walker flinched back in pain rolling onto his back.In his post-fight interview with Joe Rogan, Walker admitted he dislocated his left shoulder and said: "If I survive myself I can survive anyone."Joe Rogan joked with Walker, saying: "Well don't do that again Sir, please. You have so much potential and I'd hate to see you getting taken out of the game while celebrating."Walker's rapid rise to the pinnacle of the UFC is one to take note off.It began in light-heavyweight in August with his appearance on Dana White's Contender Series Brazil. He then went on to knock out Khalil Rountree in 1:57m in November, Justin Ledet a month later in just 15 seconds, and now at UFC 235, Cirkunov in under three minutes total.

But the Brazilian, who spoke to MMAJunkie before his fight, said that he hoped he could go the full three rounds with his opponent this time out, just to show the fans his arsenal.

“I think Misha can give me a hard fight,” Walker said.

“I hope to make three rounds against him because I need to test myself. If we fight three rounds it would be good. People can see my game and be scared.”  

Elsewhere on the card, Ben Askren submitted Robbie Lawler on his debut inside the Octagon, Cody Garbrandt was KO'd by Pedro Munhoz in a thrilling encounter, long-time welterweight champion Tyron Woodley lost his belt to Kamaru Usman after an astonishing five-round dominant performance from the Nigerian, and Jon Jones put a beating on Anthony Smith in the main event. 

Walker improved to 17-3 and 3-0 in the UFC with the victory.

For better or for worse, it lasted a matter of seconds.

Let's hope he didn't seriously injure himself so we can watch his rise to a word title and see his impressive form continue.
