Mayweather vs Guerrero: Live stream, results, and round-by-round coverage

Floyd Mayweather meets Robert Guerrero in tonight's big Showtime pay-per-view main event, and BLH will be here with live results and round-by-round coverage.

The PPV kicks off at 9:00 pm EDT, and our undercard coverage is here. I repeat, our undercard coverage is here. I repeat again, our undercard coverage is here. So don't wonder why no one's watching Santa Cruz-Munoz. They are. Just not here.

The Mayweather-Guerrero fight itself will go on around 11:00 pm EDT according to ESPN.com, but recently, the main events of these PPVs have been up closer to Midnight EDT. If you're a one-and-done PPV orderer -- which you should not be, as tonight's undercard is good -- then tune in at 11:00 to be safe, I guess.

Mayweather (43-0, 26 KO) is defending his WBC title and is the heavy favorite, with Guerrero (31-1-1, 18 KO) a former titlist at featherweight and super featherweight, who also held interim belts at lightweight and welterweight.
