UFC 73

UFC 73: Stacked was a mixed martial arts (MMA) event held by the Ultimate Fighting Championship (UFC). It took place on July 7, 2007 at the ARCO Arena in Sacramento, California and featured a total of nine bouts: four on the preliminary card and five on the main card.

In the main event, Anderson Silva put his UFC Middleweight Championship belt on the line against Nate Marquardt. The card's other championship match had Sean Sherk defending his UFC Lightweight Championship belt against Hermes Franca.

Jason Gilliam was the third choice for Chris Lytle's opponent. Originally scheduled to compete was Jeff Joslin, who withdrew due to a training injury. His replacement, Drew Fickett, also withdrew later due to injury.

Jorge Gurgel was initially reported to be facing future WEC Lightweight Champion Jamie Varner at this event, but Varner was later moved to the WEC for a planned match at WEC 27. Gurgel would instead fight Diego Saraiva on this card.
