British heavyweight trio David Haye, Tyson Fury and Dereck Chisora will all attend Wladimir Klitschko's world title bout against Alexander Povetkin on Saturday night.
The three fighters have previously stated that they would like to meet Klitschko sometime in 2014, but it is unclear whether any encounter will become a reality, despite their appearance in Moscow.
Haye fought the younger of the Klitschko brothers in 2011, losing unanimously on points, while Chisora suffered the same fate against Vitali Klitschko in 2012.
The two Brits brawled in the aftermath of Chisora's loss, leading to Klitschko to condemn their conduct, while Fury has frequently insisted that he could beat either brother if he were granted an opportunity to compete against them before they retire from the sport.
