Sage Northcutt's debut in ONE Championship lasted all of 29 seconds, as Cosmo Alexandre floored the former UFC fighter with a stiff right hand during Friday’s ONE Championship 96 event in Singapore. 

Entering the event, Alexandre (8-1) told MMA Junkie that he wasn't too concerned with Northcutt - and he proved why on Friday.

“I know that’s he’s young, strong, explosive and athletic,” Alexandre told MMA Junkie. “He used to fight in the UFC, but I’ve fought everyone in muay Thai. I fought Yodsanklai Fairtex twice. I fought the best. So this is just another fight. There’s nothing special here. I simply don’t want to lose.

“I’m training to win, regardless of my opponent. I haven’t fought MMA in some time, but I’m not too concerned.”

Northcutt, 23, walked away from UFC following three straight wins over the likes of Zak Ottow, Thibault Gouti and Michel Quinones.
