Nurmagomedov made his professional MMA debut in September 2008 and compiled four wins in under a month. On 11 October, he became the inaugural Atrium Cup tournament champion, having defeated his three opponents at the Moscow event. Over the next three years he went undefeated, finishing 11 out of 12 opponents. These included a first-round armbar finish of future Bellator title challenger Shahbulat Shamhalaev, which marked his M-1 Global debut. In 2011, he competed in seven fights for the ProFC promotion, all of which he won by TKO or submission.
A 16–0 record in the regional circuits of Russia and Ukraine generated interested from the Ultimate Fighting Championship (UFC) in signing Nurmagomedov. Later, Nurmagomedov's father revealed in an interview that due to a contract dispute with ProFC they had 11 court cases contesting the legitimacy of Nurmagomedov's UFC contract. After losing six and winning five cases, they reached an agreement and Khabib was able to continue his career.
