I mean whatever, Bigfoot called him out.
But makes little sense really. Reem was getting a title shot and failed a test.
Meanwhile, Bigfoot lost to 2 guys brutally. 2 men who were much smaller, tooled him on the feet and on the ground in Cain's case. He then faces the GREAT Travis Browne, Browne hops up and down like an idiot and injures his knee. Bigfoot proceeds to KO an immobile Travis Browne.
So that means you set up Bigfoot/Reem? Not sure why Bigfoot gets all these elite matchups. Perhaps because he is marketable beyond his talents.
