Last I heard it was looking like Brock would be able to fight again in the summer, if that is the case then there shouldn't even be an interim title, there wouldn't be any point. TUF puts title belts on hold for the same amount of length that Brock's illness would put the HW belt on hold. Dana does love the interim belts though.
I dont think belts go on hold for more than a year very often, but I could be wrong
HW: Arlovski, CroCop, Mir
