The 29 year-old decided enough was enough once the clash was called off with just two weeks’ to go, making it the third fight in a row to fail to make it to the first bell under Warren’s banner.
Fights with Liam Walsh, Jose Ocampo and now what was a mouth-watering battle with Vazquez has fallen through since September and a possible clash with 135lb king Adrien Broner looks as far away as ever.
Burns and manager Alex Morrison have now decided to take the ultimate step of walking away from Warren, becoming yet another big name to opt out following the departures of Tony Bellew, James DeGale and George Groves in recent times.
“I regret it has come to this because I have known Frank for nearly 40 years, but it has to be for Ricky’s sake,” Morrison told Scotsman.com.
“I felt we to do something to stop Ricky stagnating. Two fights have been called off after he has trained hard for them and it was not even certain that the bout with Vazquez would have gone ahead on April 20.
“In fact, I now doubt very much that fight was ever going to happen.”
The scheduled clash with Mexican Vazquez now looks dead in the water and Burns has a big decision to make on where he takes his career after a prolonged period of inactivity for the world title holder.
