Frank Warren is eager to see how Anthony Joshua reacts if he feels the power of Daniel Dubois when the pair clash later this month.
Dubois will be defending his IBF world title against Joshua, live on DAZN, with the event set to take place in front of a record crowd at Wembley Stadium.
Dubois enters the bout in impressive form following two excellent stoppage wins over Jarrell Miller and Filip Hrgovic.
Joshua is set to be a significant step up for the champion, and Warren has had his say on the bout with Dubois receiving his full backing.
"He gets countered easy, and I'll tell you something, that will be the telling point," said the Hall of Fame promoter when speaking to BoxingScene.
"Whoever gets clipped, how they react to it. Not to be knocked out, but the first solid punch that lands. How do they react to it?
"I think Joshua will go on the back foot if he gets caught and if he goes on the back foot, that's my man's fight."
