Taking place on the Oleksandr Usyk vs. Tyson Fury 2 undercard, the two British heavyweights had the chance to produce a memorable contest, and they did just that. 

In the build-up to the fight, Fisher said 'carnage' would ensue come the opening bell and in the opening rounds, the "Romford Bull" was in control. 

Thumping body shots and multiple punches tested Allen's chin, who did not seem to be affected by what was being thrown at him.

Then came round five where the fight would be turned on its head. 

Out of nowhere Fisher was down for the first time in his career and Allen was in the ascendancy, but that did not stop Fisher from rocking the "White Rhino" after a brief meeting with the canvas. 

It was clear Fisher was unsteady following the knockdown and at any moment it looked like the fight could be stopped. 

In round seven, Allen landed a number of clubbing right hands which could be felt across Riyadh's Kingdom Arena, but somehow Fisher was not going to submit to this beatdown.

While this was not the most technical display of boxing, it was an entertaining one with both men trading blows at numerous stages in the final three rounds of this 10-round affair. 

When it came to who looked in the stronger position during these exchanges, it was Allen with Fisher struggling to maintain any stable footing. 

Once the final bell sounded, many thought Allen had done enough to inflict the first defeat of Fisher's career, however, judging will become a topic of conversation once more. 

One judge scored the fight 96-93 in Allen's favour, while the two others gave Fisher the nod with a 95-94 score. 

The call was met with boos inside the Arena, while a DAZN fans poll had Allen the winner by 72% to 28%, so it looks like this result is likely to be disputed amongst boxing fans for days to come along with calls for a rematch, but whether this happens remains to be seen. 

There is however one thing for sure, whenever a rhino and bull share the same ring, carnage will unfold.
