Pulyaev blames Murzakanov's cardio for Costa loss on fighter's birthday

He also raised questions about how Costa appeared to recover so well between the second and third rounds, noting Costa seemed exhausted but returned fresh for the final frame. The commentary suggests concerns about conditioning playing a decisive role in the fight's outcome.
