Both Jiri Prochazka and Carlos Ulberg stepped on the scale without issue ahead of their UFC 327 light heavyweight main event, which takes place on April 11, 2026.
Prochazka, ranked second in the light heavyweight division, brings a 32-6-1 record into the fight. The 33-year-old Czech Republic native trains out of Jetsaam Gym Brno and is no stranger to the main event spotlight — Saturday night will mark his fifth UFC main event appearance. Standing six-foot-three with a massive 80-inch reach, Prochazka is one of the most dynamic strikers in the division, landing 5.69 significant strikes per minute at 55 percent accuracy. His only two losses over the past decade have both come against current champion Alex Pereira.
Ulberg, who fights out of New Zealand's City Kickboxing, enters this contest ranked third at light heavyweight with a 15-1 record. The 35-year-old, known as "Black Jag," has won nine straight fights heading into Saturday, and his sole career loss remains the only blemish on his UFC record. At six-foot-four and carrying a 77-inch reach, Ulberg generates an impressive 6.54 significant strikes per minute with matching 55 percent accuracy. This will be his second UFC main event.
Why it matters

- Ulberg faces comfortably the toughest test of his career, with Prochazka representing a significant jump in opponent quality after nine consecutive wins.
- Both fighters are high-volume Orthodox strikers of similar accuracy, setting up a technically intense stand-up contest between two of the sharpest hands in the 205-pound class.
