Conor McGregor smashed ANOTHER huge Ronda Rousey record with his 13-second UFC title knock-out

We don't want to sound like a broken record, but Conor McGregor just cannot stop breaking records.

The Dubliner isn't afraid to shout it from the rooftops either. We already know as well as breaking the record for the highest UFC gate receipts with $10.1million taken at the MGM Grand, his stunning KO of Jose Aldo after just 13-seconds became the fastest finish in UFC title fight history. The one-punch knock-out of former featherweight champion and pound-for-pound king Aldo beat Rousey's record by a whole second. But that's not the only record he stripped UFC golden girl Rousey of, who lost her bantamweight crown to Holly Holm last month at UFC 193. With that one quick-fire punch, McGregor has also robbed 'Rowdy' of the biggest earnings-per-second ratio in the whole organisation. Forbes report that Rousey was sitting pretty at the top of this list after her record-setting fight against Bethe Correia at UFC 190 with the former champ getting a slice of the 900,000 pay-per-view buys on top of $230,000 for the actual fight and sponsor pay. Estimates say she earned around $5million from that 34-second fight - which works out at around $147,000 per second in the Octagon. But early indications are that McGregor may have eclipsed even Rousey's huge earnings following eight-figure gate receipts, $500,000 for the fight itself and a slice of predicted record PPV estimates which could top 1.5million. McGregor is staring down the barrel of a huge pay-day from a fight which lasted little over 10 seconds. Forbes estimates (depending on PPV numbers) it could total $8million - which works out at $622,000 per second. But even modest estimates of PPV figures and earnings from sponsors would see him comfortably ahead of Rousey in the earnings-per-seconds stakes. Not bad for the Dubliner who was famously flat broke and claiming welfare cheques before his first UFC fight. No wonder he's eyeing a rematch with Aldo. He will be laughing all the way to the bank.
