 On December 27 , 2008 , at UFC 92 , Frank Mir defeated Antônio Nogueira for the Interim Heavyweight Championship and was to face Lesnar for the Undisputed UFC Heavyweight Championship at UFC 98 . Immediately after winning the Interim Heavyweight title , Mir found Lesnar in the crowd and shouted , " You 've got my belt " . Due to a knee injury to Mir , the title unification match with Lesnar that was originally slated to be the UFC 98 main event was postponed . Lesnar won the postponed rematch with Mir at UFC 100 on July 11 , 2009 , via technical knockout in the second round . The win earned Lesnar <unk> of the Year honors , with Anderson Silva , from Sherdog for 2009 . During his post @-@ match celebration , Lesnar flipped off the crowd who had been booing him . Lesnar also made a disparaging comment about the pay @-@ per @-@ view 's primary sponsor Bud Light , claiming they " won 't pay me nothin ' " and promoted Coors Light instead . Lesnar later apologized for his remarks at the post @-@ fight press conference , where he held a bottle of Bud Light and endorsed their product .
