UFC 28 marked the first UFC event to be sanctioned by the New Jersey State Athletic Control Board, held under the newly formed "Unified Rules of Mixed Martial Arts". Hence, the event was held in New Jersey, the first UFC event to be held in a Northern State. The new rules introduced new strict weight classes, resulting in the first and only UFC Super Heavyweight bout ever, between Josh Barnett and Gan McGee. The first UFC Bantamweight bout took place at UFC 26 in June 2000.
UFC 28 was the sixth straight UFC event to never see home video or DVD release, as their parent company SEG was nearing bankruptcy and almost died. UFC 28 was the last UFC event held by SEG in the US, and following UFC 29 in Japan, SEG sold the UFC to current owners Zuffa LLC.
