1991-03-18 Simon Brown w rsc 10 Maurice Blocker, Mirrage Hotel, Las Vegas, Nevada, USA - IBF/WBC. Referee: Mills Lane. Boxing brilliantly with the long left lead, Blocker (146) came within two rounds of unifying two titles before he ran out of steam in the ninth and was taken apart in the tenth. It was only in the tenth that Brown (147) had any joy, having had to wait his turn, but when it came he took it with both hands and a right-left to the head put Blocker down. On getting up and hoping to get through the session, Blocker looked to have a chance as Brown missed with just about everything he threw until tremendous left and right uppercuts saw him staggering around the ring prior to being stopped on the 2.10 mark.
Brown relinquished the IBF version of the title in May to concentrate on the WBC crown.
