It began with a straight left to the body of Yancy Medeiros.

It continued with a throw of the body of Medeiros to the ground.

It ended with a guillotine choke of Medeiros by ninth-ranked lightweight Jim Miller at UFC 172 on Saturday night at the Baltimore Arena.

"It's the night of the guillotines, I guess," Miller said.

Medeiros did not tap out, though. Rather, referee Mario Yamasaki stopped the bout once he noticed Medeiros was unconscious.

"Once he went out, I kind of knew that we was out," Miller said.

It was the first time Miller has put together back-to-back wins in the UFC since December 2010 and March 2011.

Miller was originally scheduled to fight Bobby Green, who was injured last week and had to pull out of the fight. Medeiros was originally supposed to fight Joe Ellenberger at UFC 172 but was called up to fight Miller on the pay-per-view portion of the card. (Ellenberger was then going to fight Vagner Rocha, who injured himself training this week and that fight was scrapped from the card.)
