“Callum will rise to the occasion for this fight against Bivol, without a doubt,” McGirt told The Ring. “Callum will beat Bivol with what he’s capable of. Bivol can fight, but it’s what Callum can do… he’s long, rangy and can catch Bivol when he’s bouncing in and out. Callum just has to be ready to fire.”

McGirt also believes Bivol’s performances are often dictated by the level of opposition he faces.

“Bivol fights to the capacity of his opponent,” McGirt said. “If his opponent’s good, you’re gonna get the best. If the opponent is mediocre, you’re going to get a mediocre performance. Bivol does just enough to win against mediocre guys. When the opponent is a star, he rises to the occasion.”

Smith (31-2, 22 KOs) has not fought since defeating Joshua Buatsi in February 2025 to capture the WBO interim light heavyweight title. He was scheduled to face David Morrell in April but withdrew because of an injury.

Bivol (25-1, 12 KOs) returned from back surgery in May with a one-sided 12-round decision victory over IBF mandatory challenger Michael Eifert. The win followed his split series with Artur Beterbiev, with each fighter earning a majority decision victory in their two championship bouts.

Asked what Smith’s strategy would be against Bivol, McGirt declined to reveal any details.

“It’s an ancient Chinese secret,” McGirt said with a laugh.
