Grass grows, birds fly and Manny Pacquiao fights Juan Manuel Marquez to a controversial decision.

After perhaps their most controversial bout to date -- a Pacquiao majority decision in Nov. 2011 -- the two familiar foes are set to lock horns for a fourth time next Saturday night (Dec. 8, 2012) from the MGM Grand Garden Arena in Las Vegas, Nevada.

In addition to the high-profile pay-per-view (PPV) boxing main event, which will air on HBO at 9 p.m. ET on fight night, Cuban sensation Yuriorkas Gamboa makes his long-awaited return to the ring opposite Michael Farenas, while Miguel Vazquez collides with Mercito Gesta in a lightweight title bout.

Javier Fortuna will also take on Patrick Hyland in a featherweight bout that will round out the televised PPV broadcast.

As befits another meeting between two of the biggest and most evenly-matched superstars in boxing, HBO has brought back its "24/7" series, the third episode of which premiers later tonight (Dec. 1, 2012).

For those who missed the first two, HBO has graciously put them online and you can find them below:

Remember: MMAmania will have plenty of coverage in the lead-up to this event, as well as LIVE results on fight night, which should serve as an excellent dessert once UFC on Fox 5 has finished blowing your minds.
