Paulo Costa publicly criticized Jiri Prochazka following his performance last weekend. Costa suggested that if Prochazka shows mercy in fights, he is in the wrong sport and should dedicate himself to something else. The Brazilian middleweight's harsh comments indicate disapproval of Prochazka's fighting approach. The original post notes the criticism contains significant negativity directed at the former light heavyweight champion. Costa's remarks suggest he believes Prochazka's performance lacked the killer instinct necessary for mixed martial arts competition.
Paulo Costa has taken aim at Jiri Prochazka on social media, publicly criticizing the Czech fighter's approach following Prochazka's performance last weekend.
Costa, known as "The Eraser," argued that showing mercy in mixed martial arts means a fighter simply does not belong in the sport, directing that sentiment squarely at the former light heavyweight champion. The Brazilian's comments were notably pointed, reflecting a view that Prochazka lacked the killer instinct required to compete at the highest level.

Prochazka, 33, enters this moment as the second-ranked light heavyweight contender, carrying a record of 32-6-1 for the Czech Republic. Standing six-foot-three with an 80-inch reach, he is one of the more physically imposing fighters in the 205-pound division. He lands 5.69 significant strikes per minute at a 55 percent accuracy rate, numbers that reflect his aggressive, high-volume style.
Costa, 35, competes one division below at middleweight, where he sits ranked 13th with a record of 16-4-0. The Brazilian is himself no stranger to pressure-heavy striking, landing 6.26 significant strikes per minute at 58 percent accuracy — among the sharper outputs in his weight class. Despite the divisional gap between the two fighters, Costa clearly felt moved to weigh in on what he saw as an unacceptable performance.

Why it matters
- Prochazka is ranked second at light heavyweight, so public criticism of his fighting mentality carries weight within a competitive division
- Costa's comments, while coming from a middleweight ranked 13th, draw attention to questions about finishing instinct at the top of the sport
- The exchange adds a layer of external scrutiny to Prochazka's path back toward a title shot
