Promoter Leon Margules of Warriors Boxing wishes to issue the following warnings to the fighter and those involved with former IBF junior welterweight world champion Juan "Iron Twin" Urango's supposed comeback fight on April 26 at the Centro Bancomer in Mexico City, reportedly against Mexican veteran Cristian Chavez (23-18, 11 KOs).

"Juan Urango is still under contract to me," stated Margules. "He's still under contract to Warriors boxing and does not have permission to do this fight and we intend to pursue our legal remedies and will seek redress against anyone who interferes with our contract."

Urango (22-3-1, 17 KOs) hasn't fought since a March 2010 loss against Devon Alexander.

"He fought Devon Alexander and after the fight, told me he was going to retire. I congratulated him on his retirement and told him if he ever decided to fight again, he still had a certain period of time left on his contract."

Margules says he's shocked the fighter is even attempting this without contacting his promoter, who guided the Colombian slugger to multiple regional titles, two world titles and several high-profile fights.

"I am outraged and disappointed. We took him to the world title twice. He earned way over a million dollars in the ring and had many big fights including Ricky Hatton, Devon Alexander, Randall Bailey, Andre Berto. How many boxers can say that? I don't know who is talking to him or leading him to believe he no longer has an obligation to Warriors, but they should be aware: I have an exclusive promotional contract and whoever is putting him on is interfering."
