Chris Eubank Jr vs. Avni Yildirim was a professional boxing match contested on 7 October 2017, for the IBO super middleweight championship.

At the WBSS draft Gala, held at the Grimaldi Forum in Monaco on 8 July 2017, Chris Eubank Sr., picked the undefeated Avni Yıldırım to face his son, with the winner to face the winner of the all british clash between George Groves and Jamie Cox.

During a pre fight press conference, Ahmet Öner, Yıldırım's manager, got into a one-sided confrontation with Eubank's camp.

Öner called Eubank arrogant, threatened to knock someone out, and yelled "When you laugh, you son of a bitch, I fuck your wife in your bed!"

An uppercut in the first round, caused Yildirim's knee to touch the canvas prompting referee Leszek Jankowiak to administer a ten count.
