After losing one fight yesterday, UFC Vegas 70 lost another during Friday morning’s official weigh-ins.

During the weigh-in window, promotion officials announced that Hailey Cowan had fallen ill, and would not be weighing in as a result. Her opponent, Ailin Perez, had successfully made weight earlier in the morning.

The nature of Cowan’s illness was not disclosed. The 31-year old bantamweight, a veteran of Invicta FC and LFA, was to have made her promotional debut in the fight.

Hailey Cowan won her way into the UFC on Dana White’s Contender Series last year.

Perez, a native of Argentina, came up short in her own octagon debut last September, which came against Stephanie Egger. “Fiona” lost the bout after being caught in a rear-naked choke in the second round.
