A furious mother added insult to injury when she slapped her cagefighter son after he lost a brutal MMA fight in Russia.

Anna Azovskaya, who is the coach, manager and mother of MMA fighter Viktor Kichigin, had been jumping up and down shouting instructions at him as he was pummelled by Ruslan Yamanbae.

Her son lost the fight when he was knocked out in the ring in Yekaterinburg, Russia.

In a clip of the fight, Ms Azovskaya can be seen dabbing Kichigin's face wounds with her right hand as he sits on the floor after the referee stopped Yamanbae's flurry of punches and declared the fight over.

But suddenly, the irate mother slapped her loser son across the cheek with her left hand.

She also trained Viktor's older brothers, Georgiy, Grigoriy, according the Australian Daily Telegraph.

In a recent interview with FightNights she said: 'My sons began to grow, as did conflicts with other boys, so I began to tell them that we must learn to fight. Men must fight!'

She added: 'Many athletes would like to have their loved ones next to them during difficult times, but it's not a possibility for many.'

'So I believe my children are lucky because I am always there to support them and help.'

Many of the video's 23,000 viewers expressed disgust at the way the fighter's mother reacted to her son's loss.

One said: 'God forbid anyone this. Poor boy.'

But others enjoyed the feat, wondering if perhaps the pushy parent could have done a better job in the ring than her offspring.

In response to a viewer asking why Ms Azovskaya was in the ring to watch the referee declare as the victor at the end of the fight, one YouTube user said: 'She landed more punches than her son.'
