A smile has never disappeared from a face more quickly.
All eyes were on Conor McGregor at the weigh-ins for his boxing debut against 49-0 great Floyd Mayweather following rumours during fight week that 'The Notorious' could potentially miss weight.
154lbs was the target for the super welterweight contest and McGregor seemingly had no issue as he came in at a lean 153lbs on Friday afternoon at the T-Mobile Arena.
Footage of the background of McGregor's weigh-in has since gone viral as fans reckon they spotted Mayweather Promotions CEO Leonard Ellerbe's disappointment once the Irishman's weight was announced.
It sure looked like Ellerbe was expecting McGregor to come in heavy as he sported a giddy smile of expectation when the MMA star set foot on the scales.

But once he saw the number, Ellerbe's happiness promptly disappeared and it was replaced with a concerned frown as he discovered that McGregor's weight cut was perhaps not as rough as was originally believed.
"153! 153! I'm a professional. I make weight," McGregor said.
"It's sacrifice. It's dedication. It's focus. But I make it and that's it. I'm in peak physical condition. I've put in the work as everyone can tell. I'm ready."
Mayweather came in well under the limit, with the scales reading 149.5lbs on the eve of his 50th professional bout.
