The Gamburyan vs. Gibson bout adds to the developing fight card, which takes place Sept. 27 at the MGM Grand in Las Vegas. The Glendale News-Press first reported the bout.
Gamburyan (13-8) hasn’t seen a win in his last two outings. In his last bout, the Armenian fighter dropped a unanimous decision to Nik Lentz. Previous to the Lentz loss, Gamburyan originally lost a unanimous decision to Dennis Siver, but the result was changed to a no-contest when Siver failed his post-fight drug test.
Gibson (12-4) comes into affair fresh off a first-round finish. At UFC Fight Night San Antonio, Gibson earned a technical knockout of Johnny Bedford. The win was his first in the Octagon.
