UFC 110: "Nogueira vs. Velasquez" is officially set to go down as all 18 participants competing in tomorrow night's event successfully made weight without incident earlier today inside the Acer Arena in Sydney, Australia. The weigh-ins were broadcast live on FiveKnuckles.com.

UFC 110 takes place tomorrow, Feb. 20, and the event's main card will be televised on pay-per-view beginning at 10 p.m. EST.

The event is headlined by a heavyweight bout between contenders Antonio Rodrigo Nogueira and Cain Velasquez in a bout that could determine the next challenger for UFC heavyweight champion Brock Lesnar. Both men tipped the scales to cheers from the crowd, as Nogueira came in at 233 lbs. and Velasquez weighed in at 242 lbs.

In the co-main event, middleweights Wanderlei Silva and Michael Bisping are set to meet in what is sure to be an exciting slugfest. Both men garnered the loudest ovations and also shared the most intense moment of the ceremony. As soon as Silva stepped off of the scale, UFC President Dana White immediately got between them so they would not make physical contact. The tension between the two was quite evident, and they also exchanged words after the separation. Bisping and Silva both tipped the scales at 184.8 lbs.

Other bouts on the main card include a lightweight showdown between Australian George Sotiropoulos and rejuvenated former title contender Joe Stevenson. Also, TUF 8 winner Ryan Bader will take a big step up in competition when he faces experienced veteran Keith Jardine. Also, Mirko "Cro Cop" Filipovic will look to get back on the winning track when he takes on late replacement Anthony Perosh, who is filling in for Ben Rothwell on two day's notice.
