The 29-year-old Riley (14-0, 7 KOs), ranked No. 7 among The Ring’s cruiserweight contenders for Jai Opetaia’s title, will put his European title on the line when he faces France’s Seydi Coupe (14-0, 9 KOs), his mandatory challenger, in the 12-round main event that night. DAZN will stream the MF Pro show topped by Riley versus Coupe from OVO Arena Wembley.

Riley, a native of North London, claimed his European belt in his last outing April 4, when he widely outpointed the experienced Mateusz Masternak across town at O2 Arena.

Riley, who is ranked No. 2 by the IBF, had hoped the victory over Masternak would pave the way for a world title attempt in his next bout. He has been mandated to fight David Nyika for the vacant IBF 200-pound strap, but with no agreement on that fight forthcoming, Riley has decided to stay busy by defending his European crown instead.

“It’s main event season,” Riley said. “It’s taken 14 wins and three professional titles to make it here and I look forward to owning the moment.

“I am defending what’s mine as the EBU European champion and I will put on a statement performance to show why I’m mandatory for the IBF, ranked No. 7 [by] Ring Magazine and Top 10 in three of the major world governing bodies.”

“Viddal could easily have waited patiently for his shot at the IBF world title,” Kalle Sauerland, Riley’s promoter, said. “But off the back of his Mateusz Masternak masterclass, he wanted to keep the show on the road by taking on his mandatory challenger. Coupe is unbeaten and dangerous, but Viddal is a world champion in waiting and we’re expecting a big win, live on DAZN.”

Riley-Coupe slots in at the top of a card which is already set to feature the lightweight bout between Manchester’s Zelfa Barrett (35-3, 18 KOs) and Wales’ Gavin Gwynne (19-4-2, 5 KOs). Yaser Al Ghena (16-0, 3 KOs), a junior welterweight from London, is also set to battle Darlington’s Ben Marksby (14-0, 3 KOs) on the undercard.
