Terence Crawford recently declared that boxing remains the toughest sport to compete in at the highest level.

What happened?

Crawford made this claim on social media, following Ilia Topuria's loss at UFC Freedom 250.

The four-division world champion insisted: "Still till this day, no matter what y'all say or how you feel. Boxing is still and will forever be the hardest sport to do at a top level."

Why it matters for Terence Crawford

Conor McGregor quickly responded with a brief but pointed five-word reply: "I guess we’ll never know."

This exchange is the latest chapter in an ongoing war of words between the two stars.

What comes next?

McGregor has consistently argued that elite MMA fighters are willing to cross over into boxing, while top boxers rarely make the move in the opposite direction.

He previously revealed that he attempted to secure a two-fight crossover agreement with Crawford featuring one boxing bout and one MMA fight.

According to McGregor, Crawford rejected the proposal, preferring to remain inside the boxing ring.

Crawford's comments also sparked a reaction from McGregor regarding Ilia Topuria's loss to Justin Gaethje.

McGregor suggested that Topuria effectively quit during the fight when his corner stopped the contest at the end of the fourth round.

The former UFC champion admitted it was difficult to watch but also argued that the setback could ultimately help Topuria's long-term development.

McGregor took to X and wrote: "He quit himself. Sad to see. He earned a nice stripe however tainted, he will get stronger from this beating. What a sport!"
