Zhang to prove he's the main event

'Big Bang' ready to put Parker 'to sleep' and set up world-title shot

Watch out! The "Big Bang" is about to wreak havoc in the heavyweight division.

Fresh off two convincing wins over Joe Joyce, China's heavyweight titan Zhang Zhilei will bid to earn a world-title shot by knocking out former champ Joseph Parker in his interim belt defense on Friday in Saudi Arabia.

After proving his world-class precision and finesse with two straight KOs of Joyce last year, the 40-year-old Zhang has vowed to power his way to supremacy in the stacked division, treating the bout against Parker as a steppingstone to a shot at the titles currently held by Britain's Tyson Fury (WBC) and Oleksandr Usyk (WBO, WBA and IBF) of Ukraine.
