A public disagreement has broken out between two light heavyweight contenders this week. The Jiri Prochazka Paulo Costa dispute began after Costa mentioned the former champion on social media. Prochazka claims the UFC has already offered Costa a fight against him for October or November.
Costa immediately denied ever receiving any of that specific information from the UFC itself. The public exchange escalated quickly across both fighters’ social media accounts. Here is everything confirmed about this disagreement and what it truly means for the division.
How the Dispute Started
Costa recently criticized several light heavyweight contenders while discussing his own position in the division. He questioned Magomed Ankalaev’s performance in his recent win over Bogdan Guskov. He also mocked Prochazka’s knockout loss to current champion Carlos Ulberg during the same commentary.
Prochazka responded directly through a video posted to his Instagram account. He told Costa to stop mentioning his name unless he intended to accept a fight against him. He stated plainly that he is currently waiting on the contract for that exact matchup.
What Costa Said in Response
Costa fired back publicly on social media shortly after the video circulated online. He insisted that nobody at the promotion had mentioned Prochazka’s name to him directly. He framed himself as the biggest name in a division he described as lacking excitement.
The disagreement now centers entirely on whether the UFC extended a real formal offer. Prochazka maintains the fight has already been presented directly to Costa himself. Costa maintains the complete opposite, leaving fans genuinely uncertain about which account reflects reality.
Both Fighters’ Recent Form in the Division
Prochazka enters this specific dispute with a 32-6-1 record overall in his career. He also holds a 6-3 mark specifically inside the UFC promotion itself. He lost his light heavyweight title by knockout to Carlos Ulberg back in April. That result left him searching for a real path back into contention.
Costa holds a 16-4 record overall across his entire professional fighting career. He also holds an 8-4 mark specifically inside the UFC promotion itself. He finished Azamat Murzakanov with a head kick on that exact same card. That win confirmed his successful transition up to light heavyweight.
Why This Fight Makes Sense for the Division Right Now
The light heavyweight title picture remains unsettled following an ACL injury Ulberg suffered. He is expected to miss the rest of 2026 recovering from surgery. An interim title fight has been discussed as a realistic response to fill that gap.
A win for either man in a Prochazka versus Costa matchup would strengthen a case for that interim opportunity. Ankalaev’s recent win over Guskov also factors into who else might be considered. The division has multiple contenders jockeying for position while the champion recovers.
Conclusion
The Jiri Prochazka Paulo Costa dispute remains unresolved with no official confirmation from the UFC itself. Both fighters have made their positions clear through competing public statements. Whether this fight actually gets booked may depend on which side the promotion chooses to clarify first.
