Nigeria’s Isreal Adesanya has suffered his first Ultimate Fighting Championship defeat after a 20-fight undefeated run to Polish fighter, Jan Blachowicz.

The 31-year-old was defeated after five rounds as Blachowicz retains his light-heavyweight division championship belt.

Adesanya entered the fight undefeated with a 20-0 record (15 knockouts) hoping to make history in the light-heavyweight division for the first time as a three-time UFC middleweight champion.

Both fighters were tied at 19 points apiece after the end of the first two rounds in the octagon but the Polish powerhouse made his weight count in the last two rounds to swing points in his favour.

The Stylbender began the fourth round with a big punch but fell to a takedown by his opponent, leaving the Nigerian breathing heavy under the chunky Blachowicz for a little more than three minutes.

The polish fighter ended the fifth round high with heavy punches on top of Asesanyan after another takedown as he sways the scorecard against Adesanya.
