Sponsor athletes from the UFC, fool. Come on bruh. Get your boy New Mansa in the building, let’s get it.”Prime's existing sponsorship deal with the UFC only extends to the promotion and individual athletes are not part of the same deal. However, it may not be up to Paul to decide if the beverage brand sponsors Buckley as he is only a part owner of the company with a marginal 20% stake.Check out Joaquin Buckley's message to Logan Paul on Twitter:Jed I.
