The event begins at 9pm and it will be streamed exclusively in the United States by ESPN+. Pacquiao and Matthysse are expected to be in the ring at 11:30. This is Pacquiao's first bout since he lost the WBO title to Jeff Horn almost a year ago to the day. It was a controversial decision in Horn's home country of Australia that had some wondering if Pacquiao might hang up the gloves after another disappointing defeat. He's back and sources tell me he looked fast and sharp in training camp. Pacquiao's name still carries weight in the boxing world, but there are questions as to how well he will draw behind a paywall–even one as manageable as the $4.99 monthly cost for ESPN+. Pacquiao-Horn was broadcast on ESPN as a kickoff to Top Rank's deal with the cable network. It did stellar numbers peaking at 4.4 million viewers and averaging 3.1. That fight didn't have much competition for viewers on the Independence Day weekend. This fight has a few more obstacles. In addition to the paywall, there's also a UFC event that will broadcast on Fox Sports 1 during the same timeframe. It's not a stacked UFC card. Former heavyweight champion Junior dos Santos returns to the Octagon to take on newcomer and former World Series of Fighting champ Blagoy Ivanov in his promotional debut. Also, the mildly polarizing Sage Northcutt is in the co-main event against Zak Ottow. The viewing details for Pacquiao-Matthysse came about a little late and there hasn't been a great deal of promotion for the fight, so it's possible that could hurt the bottom line viewership for the fight as well.
