Deontay Wilder has once again mocked heavyweight rival Tyson Fury for his "lineal heavyweight title." The American professional boxer said that the belt is "just stupid," adding that "they're trying to create something new in boxing."

In his recent interview with Boxing Scene, the undefeated pugilist taunted his rival for fighting 12 rounds for an "invisible title." Wilder said that "he don't have nothing, what does it mean, though? The undisputed WBC heavyweight champion added that it does not certainly mean something "at the end of the day."

Fury relinquished the last three of the four titles he won from Wladimir Klitschko in 2016. The Briton strongman vacated his WBA, WBO and IBO belts after a midlife crisis with alcohol, and drugs prompted him to seek rehab.

Last month "The Furious One" won the WBO Inter-Continental heavyweight title after knocking out Tom Schwarz at the MGM Grand Arena. He has always called himself the world's lineal heavyweight champ, and his statements have continuously irked Wilder.

Before the recent banter, Wilder has already criticized Fury for fighting a nobody. In his conversation from FightHype, he blasted the British pugilist for the "ridiculous" match-up and added that he is only interested in fighting "night-shift graveyard workers." He continued his mocking by saying that the whole thing is "bulls*** at its best."

As for his response, Fury posted a photo of him on Instagram earlier today, describing Wilder as "jealous DOSSER." The caption read "This is a big kiss to @bronzebomber AKA THE BIG jealous DOSSER,#BUMCITY #imthekingoftheworld."

Both fighters were involved in a classic slugfest in December that ended in a controversial draw. Since then, both boxers have been critical of each other, with Wilder always the first one with the insults.

Both fighters are slated for a possible rematch in 2020, but they need to beat their upcoming opponents first. Wilder is scheduled for a rematch against Luis Ortiz in November, while Fury will be defending his newly acquired belt against undefeated Otto Wallin on September 14.

Wilder has 41 wins, with 40 coming from vicious knockouts. He has arguably the best knockout ratio in the history boxing with 97.6 percent of his total fights ending in KOs.

The 6-feet-9 Fury also holds an impressive record of 28 wins, with 20 coming out of knockouts. He had already been denuded of the IBF belts twice before claiming the WBA, WBO and IBO titles from Wladimir Klitschko in 2015.
