Ladd eventually weighed in at 137 -- 2 pounds over the bantamweight limit -- but there was no way Dana White's org. was going to let Ladd take the Octagon for a catchweight bout ... with the fight being scrapped just moments ago.
This is not the first time Ladd has had a grueling experience at a weigh-in -- in 2019, she also showed serious signs of struggling as she made weight for UFC Fight Night 155.
But Ladd did not look her usual self in the Octagon after, losing in a TKO in less than a minute against Germaine de Randamie.
Here's hoping Ladd can recover and get back on the right track.
