The likeable Allen was introduced as ‘the people’s champ’ and received a warm welcome as he entered the ring.

Fisher – thanks in large part to his social media star father ‘Big John’ and their ‘bosh’ catchphrase – is one of domestic boxing’s biggest ticket sellers.

The noise turned up a notch when he made his ring walk to Take Me Home, Country Roads by John Denver, with just a small number of empty seats at the 8,000-capacity arena, nicknamed ‘Copper Bosh’ by Team Fisher.

Allen failed to land with his telegraphed overhand rights and Fisher snapped out the jab as the contest struggled to catch fire early on.

Fisher, who knocked out Alen Babic in the first round at the same venue last year, landed stinging uppercuts in the third and was given a warning for throwing a punch after the referee called break.

With the ‘Bull Army’ in full voice, the raucous atmosphere was strikingly different to the low-key first fight in Saudi Arabia.

Allen remained patient, waiting for his opening. Just like he did five months ago, he sent Fisher to the floor in the middle of the fight with brute power and determination.

Then came a highlight reel knockout which drew gasps from those in attendance.

The pair have remained friends since first sparring several years ago and Allen kept his celebrations on hold until Fisher was back on his feet.
