CNN Press Release: CNN Broadcasts HBO® Reality Series 24/7 Mayweather/Cotto

Four-Part Boxing Special Airs at Midnight ET/PT on CNN beginning Saturday, April 14

HBO’s Emmy-Award®-winning reality series ‘24/7’ is returning to CNN, which will air replays of the all-new four-part series 24/7 MAYWEATHER/COTTO, beginning Saturday, April 14 at midnight ET/PT.

In the lead-up to the blockbuster HBO Pay-Per-View® telecast on May 5 in Las Vegas when Floyd Mayweather and Miguel Cotto battle for Cotto’s world super welterweight title, CNN will present all four episodes of 24/7 MAYWEATHER/COTTO, the all-access, behind-the-scenes pass that allows viewers to step into the lives of the fighters before they step into the ring. Mayweather lives and trains in Las Vegas, NV, while Puerto Rico’s Cotto will train in Florida.

35-year-old Floyd Mayweather (42-0, 26 KOs) is a celebrated boxer making his sixth appearance on the ‘24/7’ series. Cotto, 31, (37-2, 30 KOs) has reinvigorated his career by capturing the super welterweight title and successfully defending it twice in 2011. This is Cotto’s third appearance on ‘24/7.’

Episode one will air on CNN on Saturday, April 14 at midnight ET/PT, following the HBO premiere at 9:45 p.m. ET/PT. Episode two and three will air on CNN on subsequent Saturdays – April 21 (12 midnight ET/PT) and 28 (12 midnight ET/PT). The finale will air on CNN on Friday, May 4 at 12 midnight ET/PT, less than 24 hours before the match in Las Vegas.

In the past four years, HBO’s 24/7 franchise has earned 14 Sports Emmys® for production excellence, making it the most honored sports series on television since its inception. Narrated by Liev Schreiber, the fast-moving, documentary-styled production focuses on the training, commitment and sacrifices that prizefighters make in order to realize their dreams. The turnaround time is among the quickest in television as the series follows the fighters and their teams both at camp and at home as excitement and anxiety builds for the big fight.
