Boxing is back on tonight with one of the sports biggest drawing cards, as Floyd Mayweather returns to the ring to take on Miguel Cotto for his light middleweight championship. That's not all, though. The entire event will be available for viewing TONIGHT (May 5, 2012) from the MGM Grand Garden Arena in Las Vegas, Nevada.
The show starts at roughly 7 p.m. ET with a live stream of the undercard bouts that will air online via both Yahoo! and HBO.
