UFC star Johnny Walker says he is 'ashamed' of his brother, Valter Walker, after he submitted an MMA fighter who was born without legs.
Valter Walker, nicknamed 'The Clean Machine', defeated Zion Clark in an openweight submission grappling match at Karate Contest 59 on Saturday night.
Clark has causal regression syndrome, a congenital disorder which affects the development of the lower spine and which resulted in the American being born without legs.
Walker, who often attempts to win fights by using a heel hook submission, instead submitted Clark using a rear naked choke.

He decided to let go of his opponent, who was clearly defenceless, on his first attempt at the submission, before re-applying it and forcing Clark to tap out.

It was a bizarre spectacle that left most fight fans completely baffled, with Volter - who is over twice his opponent's size, at 6ft 6in compared to 3ft 2in - then using his post-match interview to call out his brother, Johnny, for a UFC fight.
"I'm really upset because I called my brother to come here with me and he didn't come," he said. "I want to crush him!"
It wasn't long before Johnny clarified exactly why he didn't attend the fight - and he had some choice words for his brother in the process.
"I am ashamed!" he wrote in an Instagram comment. "He is choking a defenseless guy, 4-times lighter than him, and without legs, very disrespectful."
He added in Portuguese (translation via Bloody Elbow): "Get someone your size, you're shameful for the Walker legacy.
"That's why I didn't come to this fight, it wasn't a fight, it was a - I can't even give it a name. Someone tell me what it was, please.
"He doesn't deserve to use my name! He is not a Walker.
"I am very sad, I stand up for family, family is what I fight for, and he have no respect on my family my wife and my mom!"
Walker was not alone in his views on the fight, with one fan writing: "Can't believe someone allowed this to happen, I feel like I'm watching a crime."
A second asked: "How is this regulated?"
And a third added: "What are we doing here? Come on."
