There are just hours to go before Floyd "Money" Mayweather Jr. finally steps into the ring to face off against Manny "Pacman" Pacquiao. It's a fight that even sports fans who say they no longer care about boxing will be watching as two of the finest boxers of this generation finally come toe-to-toe.
Here's a brief look at what's at stake in this match:
5 -- The number of years it took to negotiate what many are billing as "The Fight of the Century." Pacquiao and Mayweather were supposed to duke it out back in 2009 but plans got held up -- as they so often do -- by disputes over money. In the end, Pacquiao agreed to receive second billing in this fight, as well as only 40 per cent of the payout. But perhaps because of the five-year wait, anticipation and will-they-or-won't-they excitement have been so built up, the fight is now expected to be the richest boxing match in history.
47 -- The number of career fights that Floyd Mayweather Jr. has seen and won. Mayweather -- hardly a humble man -- believes he is the greatest pound-for-pound fighter of all time, and while his record is impressive, he remains two wins away from tying Rocky Marciano's coveted 49-0 career record.
57 -- The number of fights Pacquiao has won. With five losses and two draws, Pacquiao may not be undefeated, but he has fought more fights than Mayweather and won more times. Pacquiao also has more knockouts to his name -- 38 compared to Mayweather's 26.
2 -- The number of years in age that separate the two fighters. Pacquiao is 36, and Mayweather is 38. Both fighters are close to retirement – or re-retirement in Mayweather's case – but Mayweather has said he believes he and Pacquiao are meeting at the pinnacle of their careers. "The time is right," he recently told The New York Times.
147 -- The number of pounds each boxer is expected to weigh for Saturday night's fight. As welterweights, the fighters must weigh at least 140 pounds at Friday night's weigh-in, but no more than 147 pounds.
4 million -- The number of viewers expected to be watching this fight. About 16,800 of those be actually be in the MGM Grand theatre; the rest will either be watching the fight from home, shelling out around $100 per household to access the pay-per-view broadcast, or paying to watch the fight at bars.
$300 million or more -- The estimates of how much money is at stake in this fight, from tickets sales, pay-per-view sales, merchandise and more. Assuming the fight lasts the full 12 rounds, Mayweather should be earning about $4 million a minute during the fight, while Pacquiao earns $3 million a minute.
60 -- The number of seconds it took for the handful of tickets that actually went on sale to sell out nine days ago. After HBO, the MGM casino and Mayweather and Pacquiao's entourages and promoters scooped up the best tickets, only 500 tickets were left to go on sale to the public. The cheapest tickets went for $1,500 and went up from there to $10,000. They're selling for considerably more in the so-called "secondary market" of scalpers.
$1 million -- The value of the actual belt that Saturday night's winner will take home. The WBC, the World Boxing Council commissioned a special belt for the match that features more than one pound of gold, and a massive medallion studded with more than 3,000 emeralds.
$25,000 -- The reported cost of Mayweather's mouthguard, which is said to be filled with diamonds and gold flecks and the pieces of $100 bills.
