Wilson Gouviea’s recent-withdrawal from a scheduled UFC 102 fight against Ed Herman has caused the UFC to shuffle several upcoming matchups, as Herman will now fight Aaron Simpson at the August 28 event, while Dan Miller, who was to fight Simpson at UFC Fight Night 19, will instead meet CB Dollaway on the September 16 card.

The matchups were both reported by MMA Madness on Monday.

Simpson (5-0, 1-0 UFC), a teammate of Dollaway’s at Arizona Combat Systems, made his WEC debut late last year with an 18-second knockout of David Avellan, then jumped to the UFC, where he defeated Tim McKenzie via first-round TKO in his April debut. Herman (15-7, 4-4 UFC) suffered losses to Demian Maia and Alan Belcher in 2008, but rebounded with a unanimous decision victory over David Loiseau in April.

The former IFL middleweight champ Miller (11-2) won three-straight bouts over Rob Kimmons, Matt Horwich, and Jake Rosholt to begin his UFC career, extending his unbeaten streak to ten-straight, but suffered a unanimous decision loss to Chael Sonnen at UFC 98 in May, his first loss in over three years. After losing to Amir Sadollah in The Ultimate Fighter 7 Finale, Dollaway won back-to-back fights over Jesse Taylor and Mike Massenzio before losing to Tom Lawlor in July at UFC 100.
