Liverpool heavyweight David Price has backed Tony Bellew following drug allegations from Ovill McKenzie.
McKenzie suggests Bellew has something to hide after he recovered quickly from punches in their fight in December.
Price told BBC Radio Merseyside: "You've got to draw a line with the pre-fight hype.
"But what a thing to say. He's clutching at straws as to why Tony got up after that punch and beat him fair and square - that's what it is."
He added: "You can't go around accusing people of being on drugs in sport without any substance."
Bellew and McKenzie will meet for their rematch on the 16th of July.
