With arguably the most hyped event in company history, UFC 168, just hours away, gamblers worldwide are scrambling to find a last-second angle to make some cash.
The final UFC event of 2013 will feature an utterly tantalizing middleweight title bout between former pound-for-pound linchpin Anderson Silva and champ Chris Weidman in the main event. Along with the co-main event, a heated women's bantamweight title fight between Ronda Rousey and Miesha Tate, the main card also includes Josh Barnett vs. Travis Browne, Jim Miller vs. Fabricio Camoes and Dustin Poirier vs. Diego Brandao.
Time is running out, but here are some last-second odds for those looking to make a wager on UFC 168.
Estevan Payan proved his toughness against Jeremy Stephens at UFC 160, but the Arizona Combat Sports standout will once again have his hands full with four-fight UFC vet Robbie Peralta.
After a win over Hiroyuki Takaya in Strikeforce, Peralta has gone unbeaten in three UFC bouts, although his second fight, against Mackens Semerzier, ended in a no contest.
Both knockout artists, Payan and Peralta each have four career losses. However, Peralta has collected 12 KOs to Payan's five.
For the first time in his UFC career, Bobby Voelker will enter a bout as a favorite.
After dropping his last two bouts to Patrick Cote and future welterweight title challenger Robbie Lawler, Voelker drew William Macario, a man with just one UFC bout under his belt and just seven pro fights.
Macario lost his UFC debut when he got submitted via arm-triangle choke by Leonardo Santos at UFC on Fuel TV 10.
Coming off a disappointing loss to Dong Hyun Kim, Siyar Bahadurzada will try to get back on track with a win over underdog John Howard, a man coming off an upset win over Uriah Hall at UFC Fight Night 26.
Bahadurzada upset Paulo Thiago with a brutal KO in his promotional debut at UFC on Fuel TV 2. Less than 11 months later, Bahadurzada dropped a unanimous decision to Kim at UFC on Fuel TV 8.
In the second fight of his second stint with the UFC, Howard holds a 4-4 record with the promotion and hasn't been a favorite in the UFC since his fight with Daniel Roberts in 2010.
After reeling off four straight wins between 2010 and 2011, Dennis Siver has fallen on hard times, dropping two of his last four bouts.
Manny Gamburyan, on the other hand, has bounced back from a three-fight losing skid to earn consecutive wins over Michihiro Omigawa and Cole Miller in 2012 and 2013, respectively.
Still, the bigger and more technical Siver, the UFC's seventh ranked featherweight, deserves to be labeled a three-to-one favorite.
Although both fighters are coming off a win, Gleison Tibau clearly has more momentum heading into UFC 168 than opponent Michael Johnson.
Tibau, a winner of 29 fights, has won three of his last four, with his lone loss in that span coming in controversial fashion against Evan Dunham at UFC 156.
Johnson, who roughed up Joe Lauzon in his last outing at UFC Fight Night 26, suffered back-to-back losses before that against Myles Jury and Reza Madadi.
There are plenty of valid reasons Chris Leben got marked as one of the most sizable underdogs at UFC 168.
Leben has lost three straight fights, as well as four of his last five, and will have to deal with the explosive, young and talented Uriah Hall in the main event of the night's prelims.
Hall, a gifted KO artist, has dropped his first two UFC fights, but Hall's struggles only solidify the oddsmakers' decision to tab Leben an underdog.
Dustin Poirier has evolved since joining American Top Team, but he's dropped two of his last four fights, and shouldn't hold such a significant edge in the odds against Brazil's first TUF winner, Diego Brandao.
Brandao has won three straight fights in the UFC and holds a 4-1 promotional record, with his lone loss coming in a unanimous decision to Darren Elkins at UFC 146.
Poirier must use the steam from his win over Erik Koch in his last bout at UFC 164 to topple the feisty Brandao.
Sporting a 1-2-1 record in the UFC, and with his only win coming over Tommy Hayden, Fabricio Camoes deserved to get deemed the second most significant underdog at UFC 168.
Camoes' opponent, Jim Miller, has won 11 fights in the UFC and holds notable wins over Melvin Guillard, Joe Lauzon and Gleison Tibau, among many others.
The odds are rightfully tight in a bout between Josh Barnett and Travis Browne, two world-ranked heavyweights who are each riding impressive two-fight winning streaks.
Barnett took out both Guelmino (arm-triangle choke) and Frank Mir (TKO) in the first round in his last two fights, and Browne KO'd both Gabriel Gonzaga and Alistair Overeem in his last two outings.
Barnett fittingly got tabbed a slight favorite, primarily on account of his edge in the experience department.
The oddsmakers clearly forecast that the UFC's first bantamweight champ, Ronda Rousey, will repeat her first performance against challenger Miesha Tate.
In their first meeting, Rousey survived an early blitz from Tate and eventually slapped on a gruesome fight-ending armbar with 33 seconds left in the first round.
Rousey has since armbarred two more challengers in the first round. Tate, who armbarred Julie Kedzie at Strikeforce: Rousey vs. Kaufman, got TKO'd by Cat Zingano in her last bout.
Despite becoming the first man to KO Anderson Silva in his illustrious 16-year career, Chris Weidman will once again face "The Spider" as a slight underdog.
At 38 years old, the oddsmakers evidently believe Silva has the tools and the experience to dethrone the 29-year-old champ.
Silva sports a 16-1 record in the UFC and an 11-1 mark in UFC title fights. Weidman, however, has just six UFC fights and 10 total bouts under his belt.
