Former Bellator MMA welterweight champion Ben Askren (12-0 MMA) will make his debut in Asia's largest promotion, ONE Fighting Championship, against PRO FC veteran Bakhtiyar Abbasov (11-2 MMA) in main event of ONE FC 15 in Kallang, Singapore on May 30.
Undefeated Askren has been released from Bellator MMA after his successful final fourth title defence against Bellator Season 7 Welterweight Tournament winner Andrey "The Spartan" Koreshkov at Bellator 97 on July 31, 2013 in Rio Rancho, New Mexico.
While Azerbaijani MMA fighter Abbasov is a world champion in combat sambo, he holds a nine-fight winning-streak where in his last he fought Anar Guseinov who he defeated after 1:15 in round one by submission (armbar) at GEFC: Light of Baku in his homecountry on December 27 last year.
