NEW YORK -- Saturday's monumental UFC 205 event is down one fight, as a welterweight bout between Donald Cerrone and Kelvin Gastelum has been scrapped.
Gastelum (12-2) revealed on social media on Friday he could not make the 171-pound weight limit and has pulled out.
The news came after Cerrone (31-7) had already stepped on the scale and made weight.
Gastelum, 25, has missed weight twice previously in his UFC career. UFC president Dana White temporarily forced him to move up to the 185-pound division last year but agreed to let him move back down after one fight.
It's a heartbreaking situation for Cerrone, who has badly wanted to fight in New York since the card was first announced. He was originally supposed to fight Robbie Lawler, but Lawler withdrew last month.
Sources said discussions already have taken place to book Cerrone to a welterweight fight against Matt Brown at UFC 206 in Toronto on Dec. 10.
Former welterweight title contender Thiago Alves also missed weight for his lightweight debut against Jim Miller. Alves weighed in at 162.6 pounds, 6.6 pounds over the limit. The fight will still go on, but Alves forfeits 20 percent of his purse.
Lightweight champion Eddie Alvarez came in at 154.6 pounds for his title defense against featherweight champion Conor McGregor. McGregor weighed in at 154.4. This is McGregor's UFC lightweight debut. His last two fights against Nate Diaz took place at welterweight.
