WBC heavyweight champion Tyson Fury, and his head trainer Sugar Hill Steward, have ripped Anthony Joshua over his promise to provide sparring help.

Back in December of 2019, Joshua made what many felt was an odd gesture - to be a part of Fury's camp as a sparring partner to assist him for the February rematch with Deontay Wilder.

The sparring session never happened.

Fury stopped Wilder in seven rounds to capture the WBC title at the MGM Grand in Las Vegas.

Fury was a bit annoyed with some of Joshua's recent comments.

Joshua stated in a recent interview that he felt Fury was not that far away from retirement.

"Fury has been professional much longer than me. He should be looking to retire soon," Joshua said. "If he wants to cement his legacy, I’m here and ready. I’ve built myself into this position."

Steward rolled his eyes at the comments.

"Anthony Joshua says a lot. He was supposed to come into training camp and train with us, I guess that goes to show how far his word goes," Steward told Behind The Gloves.

And Fury backed his trainer's statements.

"We wanted some of that action. He said he was coming, but he didn’t. We can’t really take what he says as his word anymore. If I’m too old in the tooth and I need to retire, come and retire me," Fury said.

Fury and Joshua are being positioned to face each other in 2021.

Joshua will defend his WBO, IBF, IBO, WBA world titles against Kubrat Pulev on the tentative date of December 12, and Fury is slated to fight Deontay Wilder in a trilogy fight on the tentative date of December 19.

Should both win, the two champions will begin discussions for a full division unification.
