Joshua Buatsi says there is no chance of him underestimating former Croatian amateur standout and current undefeated professional Marko Calic ahead of their ten round clash for the WBA International Light-Heavyweight crown this Sunday October 4, shown live on Sky Sports in the UK and DAZN in the US.

Rio 2016 Olympic bronze medallist Buatsi (12-0, 10 KOs) hasn't fought since he became the first man to stop Canada's Ryan Ford on the Vasyl Lomachenko vs. Luke Campbell show at The O2 in London last August, and the Anthony Joshua-backed talent will be looking to make up for lost time following over a year out of the ring.

Buatsi vs. Calic tops a big night of action that sees Chantelle Cameron (12-0, 7 KOs) land a World Title shot in her very first bout as a Matchroom fighter as she takes on Brazil’s Adriana Dos Santos Araujo (6-0, 1 KO) for the vacant WBC Super-Lightweight crown.
