All fighters successfully made weight for UFC Winnipeg, though some required second attempts. Gilbert Burns and Mike Malott both weighed in at 77.56 kg for the main event. Russians Mark Vologdin and Daria Zheleznyakova also made weight successfully. Thiago Moises and John Castaneda made weight on their second attempts. Castaneda had requested a catchweight up to 63 kg the previous evening, which Vologdin agreed to, and Castaneda will forfeit 30% of his purse to Vologdin as a result.
The UFC Winnipeg card is set after weigh-ins concluded on April 17, though featherweight John Castaneda came in over the limit and will pay a financial penalty before his bout gets underway.

Gilbert Burns, the 39-year-old Brazilian welterweight ranked 13th in the division, tipped the scales at 77.56 kg for the main event, matching his opponent Mike Malott pound for pound. Burns carries a 22-10-0 record and trains out of Kill Cliff FC. Fighting out of an orthodox stance with a 71-inch reach, he averages 3.15 significant strikes per minute and adds a grappling dimension with 2.12 takedown attempts per 15 minutes.

Thiago Moises, a 31-year-old Brazilian lightweight from American Top Team, needed a second attempt before hitting his mark. The 19-10-0 veteran stands five-foot-nine with a 70-inch reach and is a notable submission threat, averaging 1.1 submission attempts per 15 minutes.

John Castaneda, the 34-year-old American known as "Sexi Mexi," also required a second trip to the scale after requesting a catchweight allowance of up to 63 kg the night before. His opponent, Mark Vologdin, agreed to the adjusted limit, but Castaneda's failure to make even that mark means he will forfeit 30 percent of his purse to the Russian fighter. Castaneda holds a 21-8-1 record and is among the more active strikers on the card, landing 4.42 significant strikes per minute at 50 percent accuracy.

Why it matters
- Burns and Malott hit the same number on the scale, setting up a clean-weight welterweight main event
- Castaneda's purse penalty adds a financial consequence to what was already a concession by Vologdin in accepting the catchweight
- The weight miss raises questions about Castaneda's preparation heading into the fight itself
