Oleksandr Usyk’s representatives have formally issued a complaint regarding the ring canvas, which is going to be used on fight night for the anticipated undisputed heavyweight title fight against Tyson Fury. 

The issue of concern for Usyk’s team is specifically surrounding the structure and stitching of the canvas, and was confirmed to Sky Sports News on the ground in Riyadh by a Usyk representative. 

The construction of the canvas, which is required to accommodate sponsorship placements upon the material, is sown together in four parts, which leaves a seam approximately 1mm in depth once constructed. 

Usyk believes the seam's width and depth could become a potential trip hazard during the heavyweight fight. 

According to Sky Sports reporter Ben Ransom, at some point today, Usyk will inspect the canvas that will be used for the fight.
