Paulo Costa took aim at Jiri Prochazka on social media following the Czech fighter's performance last weekend, arguing that any fighter who shows mercy inside the cage has no place in the sport.
Costa, nicknamed "The Eraser," competes at middleweight and holds a 16-4-0 record. The 35-year-old Brazilian, who trains out of Team Borracha, is currently ranked 13th in his division. Known for his aggressive output, Costa lands 6.26 significant strikes per minute at a 58 percent accuracy rate, numbers that underline his philosophy of unrelenting forward pressure.

Prochazka, by contrast, competes two weight classes above at light heavyweight, where the 33-year-old Czech sits at number two in the divisional rankings. Standing 191 centimeters tall with an 80-inch reach, the Jetsaam Gym Brno product is one of the most dangerous strikers in the UFC, averaging 5.69 significant strikes per minute at 55 percent accuracy. His current record stands at 32-6-1.
Costa's remarks drew a divided response online. Some members of the MMA community sided with his assessment, while others felt the criticism was excessive and that too much negativity was being directed at Prochazka. Costa did not elaborate on the specific moments from Prochazka's performance that prompted his comments, but made clear his belief that fighters must commit fully once the cage door closes.

Why it matters
- Prochazka is ranked second at light heavyweight, meaning public criticism from a fellow fighter keeps scrutiny on his recent showing at a critical point in his divisional standing
- Costa's outspoken nature and high-volume striking style give his opinion on fighting aggression a degree of credibility with portions of the fanbase
- The cross-divisional nature of the callout means no immediate matchmaking consequence, but the exchange adds to Prochazka's current moment in the spotlight
