Dan Miller vs Aaron Simpson possible for UFC Fight Night 19 on Sept. 16

It's getting to be rather standard for UFC matchmaker Joe Silva: When in a pinch and in need of a replacement fighter on short notice, call AMA Fight Club in New Jersey and get one of the Miller brothers to step up.

MMAmania.com has learned that Dan Miller (11-2) will likely replace Ed Herman against Aaron Simpson (5-0) at UFC Fight Night 19: "Diaz vs. Guillard" from the Cox Convention Center in Oklahoma City, Okla., on Sept. 16.

"Short Fuse" was needed to plug a gap of his own when James Irvin came up lame once again and was forced out of his middleweight tilt against Wilson Gouveia at UFC 102 later this month. That left Simpson temporarily opponentless ... until now.

Miller, a Brazilian jiu-jitsu brown belt, recently had has red-hot three-fight UFC win streak snapped when he faced off against Chael Sonnen at UFC 98 back in May. He was supposed to tangle with Yushin Okami, which would have likely vaulted him to the top of the division with a win.

However, "Thunder" got hurt and Miller accepted the bout against the Team Quest product on short notice. It didn't go his way. Now Miller will look to get back on track against the UFC sophomore.

Miller defeated Rob Kimmons via first round submission in his promotional debut at UFC Fight Night 15 in September 2008. Four weeks later he followed that up with an encore performance, stepping in for an injured Ricardo Almeida to topple Matt Horwich via unanimous decision at UFC 90: "Silva vs. Cote."

Before the Sonnen bout, the former International Fight League Champion (IFL) filled in again as a replacement to school blue chip prospect, Jake Rosholt, via submission (guillotine choke) at UFC Fight Night 17.

Simpson is a a one-fight WEC veteran who made his transition to the UFC when the sister promotion folded its heavier divisions. His UFC debut came at UFC Fight Night 18, where "A-Train" needed just 1:40 of the opening frame to earn a technical knockout victory over Tim McKenzie.

In fact, all five of the two-time All-American wrestler’s wins have ended in a (technical) knockout, with only one fight making it out of the first round.

"Diaz vs. Guillard" will serve as the lead-in to the tenth season of The Ultimate Fighter (TUF) and will feature a main event between hungry lightweight up-and-comers and former TUF grads Nate Diaz and Melvin "The Young Assassin" Guillard.

In addition, Roger "El Matador" Huerta will throwdown for perhaps the last time inside the Octagon as he tries to leave on a high note against the stifling super-wrestler Gray "The Bully" Maynard. Nate Quarry, Carlos Condit and Chris Lytle are also scheduled to compete.
