HBO Sports suffered a blow on Friday as Top Rank promoter Bob Arum closed a deal to broadcast the pay-per-view fight between Manny Pacquiao and “Sugar” Shane Mosley according to multiple sources.

Dan Rafael of ESPN.com was the first to break the story while conducting his weekly chat on the website.
