Hrunov, who bid a whopping $23million to stage the fight, explained to WBN yesterday that he is happy with Klitschko being tested by the German Nation Anti-Doping (NADA), but wants Povetkin to use Russian-based RUSADA.
Boente is thought to be sceptical about the total involvment of RUSADA for the proposed October 5 bout in Moscow though and Hrunov now has yet another problem to solve before the June 7 deadline.
With Hrunov making attempts to bend for Boente without success, the argument looks set to rumble on as both sides attempt to thrash out a deal before Friday.
