The two big men are expected to go head to head when the UFC returns to Brazil, likely in June. MMAWeekly.com confirmed the fight, first reported by MMAFighting, with independent sources.
Werdum (15-5-1) made his successful Octagon return at UFC 143 on Super Bowl weekend, scoring a unanimous decision victory over Roy Nelson.
He was 2-2 in his previous UFC stint, sent packing by current UFC heavyweight champion Junior dos Santos. Werdum was 3-1 while fighting under the Strikeforce banner, losing only to then champion Alistair Overeem, but defeating former top heavyweight Fedor Emelianenko.
Russow (15-1) has been in the UFC for nearly three years, but has just four fights to his credit. Of course, he has won all four of those fights.
Having defeated John-Olav Einemo at UFC on Fox 2 in January, Russow will finally start stepping up the heavyweight ladder. Werdum will be a stern test for the Midwesterner, providing Russow an opportunity to launch himself into the ranks of title contender.
Anderson Silva is expected to defend his UFC middleweight title against Chael Sonnen in the main event when the promotion returns to Brazil, but thus far, a date and location have yet to be determined.
