Deontay Wilder set for comeback fight in New York in October, one year after his trilogy defeat to Tyson Fury

But the American is now expected to make his comeback later this year against experienced Finnish heavyweight Robert Helenius.

Wilder, 36, has recently posted videos to Instagram of him training at his gym in his hometown of Tuscaloosa, Alabama as he prepares to make his return.

His opponent Helenius, 38, holds a professional record of 31-3, with one of those defeats coming against British heavyweight Dillian Whyte in 2017.

Helenius is on a three-fight winning streak and last beat Polish-American fighter Adam Kownacki in a rematch in October.

Back in May, Wilder confirmed that he planned to return to boxing in the future.

"I can't stop right now. I must continue with my journey," said the former WBC heavyweight champion.

"I love you guys so much. I can't end it like this. This journey's not over with. I must continue my journey."

Fans are split over whether Helenius represents a tough challenge for Wilder in his comeback fight.

"Wilder's back to his comfort zone, I see. Would've been interested to see him V [Andy] Ruiz, maybe even [Dillian] Whyte. But this? Nah…," wrote one fan on Twitter.

But another replied: "Wilder has just come off 2 very punishing KO loses in a row mate. Helenius if he is in the mood is not a walk in the park."
