Zach Parker and John Ryder look set to deliver a brilliant battle on Saturday night as they compete for the interim WBO title at 168lbs.
The winner of this contest puts himself in serious contention to challenge Canelo Alvarez for the full title at some stage in 2023 so the stakes couldn't be higher.
Can Ryder maintain his impressive run of form? Or will Parker announce himself on the world scene?
The main card is set to get underway at 2 p.m. ET / 7 p.m. GMT with the main event ringwalks scheduled for 5 p.m. ET in the U.S., and 10 p.m. GMT in the UK. These timings could change due to the length of the undercard fights.
US coverage is available on ESPN+, while those in the UK can watch on BT Sport.
The fight takes place at the O2 Arena in London, England.
