The flyweight division takes center stage on the early prelims of UFC 324 as former title challenger Alex Perez (25-10) aims to rebound from back-to-back losses against surging contender Charles Johnson (18-7). Perez, a technical striker with solid grappling, returns after a tough 2025 marked by a submission loss and injury setbacks, facing a confident Johnson who’s riding a wave of finishes and decision wins. Johnson, known for his volume striking and durability, looks to crack the top 10 with a win over the veteran. This matchup could be a high-paced striking affair if Perez dictates range or turn into a grind if Johnson closes distance. No prior history or bad blood, but Perez’s experience vs. Johnson’s momentum adds intrigue to a card headlined by Justin Gaethje vs. Paddy Pimblett for the interim lightweight title.

Fighter Matchups
This flyweight (125 lbs) early prelim bout pits Perez’s veteran grappling and submission skills against Johnson’s volume striking and durability. Perez (5’6″, 65″ reach, 33 years old) lands 4.8 significant strikes per minute at 52% accuracy, with strong takedowns (2.1 per 15 minutes at 48% success) and submissions (7 career subs, 28% of wins). He’s a switch-stance fighter who excels in scrambles and ground control. Johnson (5’9″, 70″ reach, 35 years old) absorbs 4.2 strikes per minute but counters with 5.2 at 58% accuracy, boasting solid takedown defense (75%) and knockout power (8 KOs, 44% of wins). Styles clash: Perez’s pressure and ground game vs. Johnson’s range and cardio; if Perez closes, his subs threaten, but Johnson’s height/reach could keep it standing for a decision.
