Watch: Mayweather calls McGregor 'heavy,' doubts he'll make weight

Saturday's superfight between Floyd Mayweather and Conor McGregor is slated to be contested at 154 pounds. But, according to "Money," the Irishman is too heavy and will miss the target.

There's no official word on whether McGregor is actually overweight or not, but if that's indeed true, two scenarios could play out.

First, Mcgregor would face significant fines in order to box, or Mayweather would have the option of turning down the fight.

If McGregor misses weight, the latter almost assuredly won't happen, as Mayweather would therefore forgo his massive payday - and we all know how much he likes to flaunt his cash.

The official weigh-in is set to go Friday evening from Vegas.
