Zach Parker tops the bill on a brilliant night of boxing at London's O2 Arena on Saturday night as he battles John Ryder for the interim WBO super-middleweight championship, exclusively live on BT Sport.

Parker, 22-0 (16 KOs), will be looking to produce a statement performance to complete a meteoric rise through the 168lb division with success on his first attempt at world level.

However, he'll need to be on top form against a skilled veteran like Ryder with the Islington man having been there, done that and got the t-shirt at the highest level over the past few years.

Ryder previously held the WBA version of the interim super-middleweight title and once challenged for the full crown against Liverpool's Callum Smith in 2019, only denied a victory by a controversial decision on the scorecards.

Also in action on Saturday night, rising stars Hamza Sheeraz, Dennis McCann and Sam Noakes, as well as Pierce O'Leary, the super-lightweight prospect being tipped for the very top by promoter Frank Warren.

It all goes down from 7pm on Saturday night, so read on to find out all the ways you can watch Parker vs Ryder across the BT Sport network this weekend.
