JJ Aldrich VS Regina Tarin

Regina Tarin defeated JJ Aldrich by unanimous decision (29-28, 29-28, 29-28) in a flyweight prelim at Noche UFC on September 12, 2026. Tarin dictated the fight from the opening bell with a consistent jab and leg kicks, using her reach advantage to control distance across all three rounds. Aldrich attempted multiple takedowns throughout the fight but converted none, and Tarin finished the first round with elbows in the clinch after stuffing one of those attempts. In the third, Aldrich pressed forward needing a finish, but Tarin absorbed the urgency and won the exchanges even while dealing with a bloody nose. The win keeps Tarin undefeated at 9-0, her second Octagon appearance against a ten-year UFC veteran.

JJ Aldrich enters on a two-fight winning streak after back-to-back decisions over Andrea Lee and Jamey-Lyn Horth, bringing solid veteran form to this flyweight bout, while Regina Tarin arrives as the betting favorite after putting on a striking clinic in Mexico City against Ernesta Kareckaite, landing 125 strikes in a dominant performance. Tarin's recent volume and output represent the primary threat to Aldrich's momentum as both women target higher divisional positioning.
