Paulo Costa has publicly criticized Jiri Prochazka following his recent performance, specifically targeting the Czech fighter's tendency to show mercy in the octagon. Costa stated that if a fighter has mercy in him, he is in the wrong sport and should dedicate himself to something else entirely. The comments come after Prochazka's recent fight where he appeared to ease up on his opponent. Costa's harsh criticism reflects his belief that MMA requires a ruthless approach without compassion during competition. The Brazilian middleweight's comments have drawn mixed reactions from fans regarding whether his assessment is fair or constitutes excessive negativity toward Prochazka.
Paulo Costa has taken aim at Jiri Prochazka, publicly challenging the Czech light heavyweight contender's in-cage demeanor following Prochazka's most recent octagon appearance.
Costa, known as "The Eraser," stated that any fighter who shows mercy during competition is in the wrong sport entirely and should pursue something else. The Brazilian made clear his view that MMA demands a ruthless, compassion-free approach once the cage door closes, after Prochazka appeared to ease up on his opponent during his latest bout.

Costa enters the conversation as a ranked middleweight, sitting thirteenth in his division at 35 years old with a professional record of 16-4-0. The six-foot-one Brazilian trains out of Team Borracha and is one of the more aggressive strikers at 185 pounds, landing 6.26 significant strikes per minute at a 58 percent accuracy rate.
Prochazka, the man on the receiving end of the criticism, holds a 32-6-1 record and is ranked second in the light heavyweight division. The 33-year-old Czech fighter out of Jetsaam Gym Brno stands six-foot-three with an 80-inch reach and brings his own considerable striking volume, landing 5.69 significant strikes per minute at 55 percent accuracy. His record and ranking make him one of the most accomplished fighters in the 205-pound division.

Why it matters
- Costa's comments reignite a debate about sportsmanship versus ruthlessness in professional MMA
- Prochazka's number-two ranking in light heavyweight means any controversy surrounding him carries divisional weight
- The criticism comes from a different weight class, adding an unusual cross-divisional dimension to the exchange
- Fan and media reaction has been divided, with some viewing Costa's stance as principled and others seeing it as unwarranted criticism
