UNBEATEN Eduardo Ramirez has been unveiled as Lee Selby’s opponent for his IBF world featherweight title defence at London’s Copper Box Arena on December 9.

Mexico's Ramirez, 24, boasts a record of 20 wins, seven coming inside the distance, and three draws, while one bout was ruled a no-contest.

His last outing came in late September when he drew with Cuban Leduan Barthelemy, another undefeated fighter, in Las Vegas.

“Ramirez is a very good unbeaten fighter and he comes from a good stable,” said St Joseph's star Selby, 30, who is making the fourth defence of his crown.

“He’s trained by Fernando Montiel’s brother – Fernando was a former challenger of mine and his brother is a very experienced coach.

“He (Ramirez) has a decent ranking with the IBF and you don’t get there by accident, he’s worked his way into the mix and he’s going to give me a tough test.

“He’s a southpaw which is another challenge for me."

Selby added: “There’s a lot of pressure on this fight, one loss will mess up my whole career.

“There’s massive fights to be made against Josh Warrington and Carl Frampton next year so it’s vital that I come through this fight.

“This show has everything, you have two of the best technical boxers in the country in myself and (James) DeGale, and then you have two of the best prospects in the country in (Anthony) Yarde and (Daniel) Dubois.

“I’m proud and honoured to be a part of this bill.”

Meanwhile, DeGale will make the fourth defence of his IBF super-middleweight title against Caleb Truax.

A native of Osseo, Minnesota, Truax has mixed it with world-class operators such as former WBC super-middle champion Anthony Dirrell and former WBA middleweight king Danny Jacobs.
