Warren was surprised when he learned that Bruno had announced that he would fight on in search of another world title. Warren, who promoted Bruno's last contest - the defeat by Mike Tyson in Las Vegas four months ago - said: "It is up to him what he wants to do. He certainly hasn't discussed it with me.
"One thing is for certain. He will have to prove himself again with a clash against a top-rated opponent before he will be considered for a world title. He certainly isn't going to jump the queue ahead of people like the British champion, Scott Welch."
Bruno has already informed the promoter Don King and would consider taking on Tyson again, although the new World Boxing Organisation champion, Henry Akinwande, is a more likely opponent.
Bruno said: "I want to fight on. I love what I do. I want to be the first British heavyweight fighter to win two world titles. My desire has not gone."Reuse content
