All rumors point to Money fighting Berto or Khan on CBS. I'll be honest, I've had a hunch for a while that #49 would be on PBC on CBS.
PBC is Haymon's baby and CBS owns Showtime, so it's logistically feasible. On top of that, Floyd knows that PPV buys for his next fight will crash through the floor due to a dearth of marketable opponents and casual backlash to the Manny fight. Apart from his zero, Floyd is most proud of his buys. On primetime television, they can sell it as bringing boxing's biggest A-side to the fans free-of-charge, without the worry of low PPV buys in the shadow of the Cotto-Canelo behemoth (which will surely crack top five all-time buys).
