British heavyweight Tom Aspinall made short work of his opponent in his octagon debut, stopping Jake Collier in just 45 seconds on the UFC on ESPN 14 prelims.

Aspinall that cracked Collier with knee up the middle and followed it with a one-two that sent Collier teetering to the mat. No follow-up was needed from the Brit, whose training partners back home include UFC on ESPN 14 headliner Darren Till.

Aspinall has won four straight including a successful octagon debut. Afterward, he called out fellow heavyweight Sergey Spivac, who outpointed Carlos Felipe this past week at UFC Fight Island 2.

Collier continues to bounce between wins and losses in the octagon, going back to the drawing board after a decision win over Marcel Fortuna in a light heavyweight bout back in 2017.
