Pacquiao might be calling it quits after Saturday night in Las Vegas

Pacquiao, age 37, is scheduled to face Timothy Bradley, age 32, for the third time in four years at the MGM Grand Garden Arena on April 8th. The bout will be televised live on HBO pay-per-view. Pacquiao is favored by the oddsmakers around 2 to 1, but Bradley looked better than ever in his last fight and Pacquiao is coming off both a loss and shoulder surgery.

The two are technically split at one win apiece, though almost everyone besides two of the three ringside judges attheir first meeting in 2012, Duane Ford and C.J. Ross, believe Pacquiao has never lost to Bradley.

The fight was hotly disputed and led to various investigations by commissions and sanctioning bodies.

Pacquiao has said he will retire after Saturday night, though fighters often say such things without following through on it. Still, Pacquiao is old by boxing standards and with Floyd Mayweather retiring after defeating Pacquiao last year in the so-called "Fight of the Century" it seems reasonable that Pacquiao might follow suit.

Arguably the most popular and exciting fighter of the era, the Filipino superstar has won world titles in eight different weight classes. Win, lose, or draw on Saturday, Pacquiao's legacyis secure.

Both Pacquiao and Bradley are ranked among the top 10 fighters in boxing pound-for-pound today, and they are ranked No.

1 and No. 2 by the Transnational Boxing Rankings Board at 147 pounds, meaning the winner of the fight will become the lineal welterweight champion. That crown wasvacated last year by a retiring Mayweather.

If Pacquiao wins on Saturday, there are a few fights out there that might intrigue him enough to stay active as a fighter.

First, a fifth battle with his great rival, Juan Manuel Marquez, would probably be the most scintillating option. Pacquiao is 2-1-1 against the 42-year-old Mexican, but was knockedout cold by Marquez in Round 6 of their last fight.

If Mayweather comes out of retirement, even other fighters think the only person he'd come back to face would be Pacquiao in a rematch of one of the most hyped fights in history.

Finally, up-and-comer Terence Crawford, who is also promoted by Pacquiao's promoter, Bob Arum, would be one of Pacquiao's greatest tests. Crawford, age 28, appears to be on his way to superstardom. Would an aging Pacquiao have what it takes to keep Crawford from ascending to the top of the sport?

Whatever happens, we know one thing for sure: Pacquiao has at least one more fight left, and it's Saturday night.
