Early career

At the Emir Fighting Championship tournament, which took place in December 2017, Jojua fought for the championship belt, and she managed to agree with the organizers to include Avsaragova in the card - everyone was satisfied. The former participant of the wrestling battles was also matched with a debutante, Alina Makarova, who lasted less than two minutes, falling into the armbar. It seemed that such a bright performance promises Diana a bright future, but she soon suffered a knee injury and dropped out of competitive sports until 2019.^{[2][10][11][6][7]}

After rehabilitation and preparation, Diana performed at the Titan Global Championship, against Anna Lurchenkova, with whom they had a full three-round duel. Having won another victory, the native of Nart got a manager who began to look for interesting offers for her. Some Russian leagues, as well as Invicta FC, considered Avsaragova's candidacy, but due to the pandemic, her next fights were canceled one after another. While training at home and watching what was happening in the world of mixed martial arts, the athlete received a call from her representative who asked if she wanted to fight in Bellator? The answer was yes.^{[2][10][11][6][7]}
