Ray Borg missed weight Friday for the fourth time in 11 UFC fights ahead of his flyweight bout against Rogerio Bontorin at UFC Rio Rancho.
"The Tazmexican Devil" weighed in at 128 pounds, two over the divisional limit. He was also 128 on his second attempt.
"Sorry to my opponent and his team for the unprofessionalism," Borg wrote on Instagram.
The former 125-pound title challenger was heavy for flyweight tilts against Geane Herrera in 2015 and Louis Smolka in 2016. Borg also missed weight for a bantamweight bout against Casey Kenney in 2019.
After losing to Kenney last year, Borg vowed to retire if he ever missed weight again. But the 26-year-old said Friday he's not thinking about his promise heading into Saturday's clash against Bontorin.
Borg said he was the "most disciplined" he's been for his fight at UFC Rio Rancho.
"The more we started cutting the less that started to come off," Borg wrote. "We were dedicated to making the weight and took the extra hour they gave us and did what we could with it. We asked for more time with all the intentions in the world to make the weight, but unfortunately they only allowed us an hour."
UFC Rio Rancho will be headlined by a light heavyweight bout between Corey Anderson and Jan Blachowicz.
