No. 5-ranked and former UFC Strawweight title challenger Amanda Lemos was scheduled to face rising contender Gillian Robertson on the UFC Vegas 112 “Featured Prelim” this past weekend (Sat., Dec. 13, 2025) at the UFC Apex. However, Lemos was pulled from the card on the day of the event, leaving fans and her opponent frustrated —Robertson was very upset about the cancellation.
The Brazilian later explained the situation on Instagram.
“Hey guys, just stopping by to let you know that my fight was canceled. On Thursday, a little bump appeared on my mouth and I don’t know what it was,” Lemos said. “The athletic commission decided to cancel the fight because they don’t know what it was. So now the fight has been rescheduled. Obviously, I’m sad, I was super prepared, super confident, but I don’t have control over it. Thank you for the support, I’ll be back, God willing.”
Fans immediately noticed the bump on her lip and automatically speculated that it was a cold sore, a form of herpes.
While unconfirmed, cold sores have previously led to fight cancellations. Fighters on the last two seasons of The Ultimate Fighter were pulled for similar issues, and earlier this year, Light Heavyweight Rodolfo Viera withdrew 30 minutes before his fight due to a herpes-related cold sore.
Lemos will now have time to address the issue. She is rebooked against Robertson for UFC Vegas 114 on March 14, 2026, though she previously indicated she was fighting on Feb. 7.
