Boos filled the MGM Grand Garden Arena Friday as UFC bantamweight champion Dominick Cruz made weight for his promotional debut.
If Cruz has his way, the boos won't stop Saturday.
Cruz (17-1) looks to avenge the only loss of his career this weekend when he faces fan-favorite Urijah Faber (25-4) in the main event of UFC 132. The two fought as featherweights in 2007, with Faber taking a first-round submission win.
"I've been waiting four years for this," Cruz said. "I'm going to keep that belt. I'm going to whoop him. So, all you fans who are booing, get ready to boo more."
The champion came in at 134 pounds for what is to be the first bantamweight title fight in UFC history. Faber weighed-in right at the 135-pound limit.
"It's going to be a war and I'm ready for a battle," Faber said.
The UFC 132 main event marks a landmark first for the organization, but the card certainly doesn't lack a few old familiar faces.
Former light heavyweight champion Tito Ortiz (15-8-1) received an equal mix of cheers and boos from the Las Vegas crowd. Ortiz is looking to record a win for the first time since October 2006.
Dana White said on record earlier in the week that Ortiz's career with the organization will be over if he's unable to defeat Ryan Bader (12-1). Both Ortiz and Bader came in at 205.
Middleweight Wanderlei Silva (33-10-1), another UFC veteran, weighed-in at 186 pounds for his co-main event fight against Chris Leben (25-7). Silva seeks to score back-to-back wins for the first time since 2006.
All 22 fighters made weight for the UFC 132 card.
