ACA president Magomed Bibulatov made several significant announcements at a press conference in Saint Petersburg. Abdul-Aziz Abdulvakhabov has vacated the lightweight championship belt, with Daud Shaikhaev promoted from interim to undisputed champion. For ACA 204 in Omsk this July, the main event will feature Shlemenko vs. Emeev, with Shurkevich vs. Dudaev as co-main and additional bouts including Khabibullin vs. Grozin and Matmuratov vs. Sulumov. ACA 206 in Moscow this August will showcase two title fights: A. Vakhaev vs. Aliakbari as the main event and Shaikhaev vs. B. Tumenov as the co-main event.
ACA president Magomed Bibulatov used a press conference in Saint Petersburg to announce a series of major organizational changes and upcoming event cards, including title-fight shake-ups and stacked lineups for two forthcoming shows.
On the championship front, Abdul-Aziz Abdulvakhabov has vacated the ACA lightweight title, with interim champion Daud Shaikhaev elevated to undisputed champion as a result. Shaikhaev will not have long to enjoy the full belt, however, as he is already booked to defend it against B. Tumenov at ACA 206 in Moscow this August.

That same Moscow card will be headlined by a heavyweight title fight between A. Vakhaev and Amir Aliakbari. The Iranian fighter carries a record of 10-1-0 and stands six-foot-three, or 191 centimeters, bringing size and experience to the ACA 206 main event at age 42.
Before Moscow, ACA 204 heads to Omsk in July with a card anchored by a middleweight clash between Alexander Shlemenko and Emeev. Shlemenko, known as "Storm," is one of Russian MMA's most decorated veterans. The 42-year-old boasts a remarkable record of 56-9-0 and lands 4.36 significant strikes per minute at 60 percent accuracy, numbers that reflect a career built on relentless offensive output. He trains out of his own Storm Shlemenko Fight Team. The Omsk card also features Shurkevich vs. Dudaev as co-main event, with Khabibullin vs. Grozin and Matmuratov vs. Sulumov rounding out the announced bouts.

Why it matters
- The Abdulvakhabov vacancy reshapes the ACA lightweight division, with Shaikhaev now holding full championship status heading into his August defense.
- Shlemenko vs. Emeev gives the Omsk crowd a marquee name in one of MMA's most active and decorated fighters at middleweight.
- Two title fights anchoring ACA 206 in Moscow signals the organization's intent to make its summer schedule a major showcase event.
