Cathal Pendred was on the button with his UFC weigh-in, in the early hours of this morning, ahead of his welterweight bout with Mexico's Augusto Montano.

'The Punisher' weighed in at 170 and faced off against the hometown favourite before dashing back to his hotel to pile some pounds back on.

Gaining weight after a weigh-in is a well-todden route in the UFC but Pendred's feat of weight gain is pretty impressive.

21 pounds in three hours. That's a lot of carbs, and fluids.

Here is the full video of the weigh-ins. Pendred and Montano grace the screen at the seven-minute mark.
