The Fury vs. Wilder feud could potentially head to the next level, as their younger brothers are now trading words.

Tommy Fury, the younger brother of WBC heavyweight champion Tyson Fury, has sent a warning to Marsellos Wilder, the younger brother of former champion Deontay Wilder.

Tommy Fury, 21-years-old, returned to the ring this past Friday and scored a big knockout of Genadij Krajevskij.

The win raised his undefeated record to 4-0 with 3 of those wins by knockout.

Marsellos Wilder, 31-years-old, has been out of the ring since November 2019, when he was knocked out by Dustin Long in four rounds.

The loss dropped his record to 5-2, with the other defeat also being a knockout loss which took place in January of the same year.

"If his brother wants the same as Deontay got, then he can get it. I see a lot of people tweeting about wanting to fight me but I never saw that before I went into Love Island so I know what they are after," Tommy Fury said.

"If Marsellos Wilder is one of those then I will happily oblige. My advice for him would be to keep quiet and stay in America where he can try to help his brother recover from what Tyson did to him, fair and square."

Tyson Fury is expected to return to the ring on December 5.

Back in February, he dropped and stopped Deontay Wilder in seven rounds to capture the WBC world title. They fought to a controversial twelve round split draw in December of 2018.

Deontay has since made several cheating allegations against Tyson - including a claim that Tyson loaded his gloves.

There was a contractual clause to force a trilogy bout, but the two sides are now entangled in a legal battle. Deontay Wilder believes the clause is still valid, while Tyson Fury and his handlers believe the clause has expired.
