Frank Warren targets Bernard Hopkins for Nathan Cleverly

Boxing promoter Frank Warren has said that he is targeting a summer fight for WBO light-heavyweight champion Nathan Cleverly and veteran Bernard Hopkins.

Cleverly beat Tommy Karpency on Saturday in his third defence of the title.

"Nathan is coming on in leaps and bounds," Warren said. "All our attention will now of course turn to April 28 and the Bernard Hopkins versus Chad Dawson fight .

"Then we will be making a big decision about a fight in the summer.

"Talks are actually underway with the Cardiff City Stadium as we're looking to stage a summer event so that would be great, it's a fantastic arena."

Cleverly has an unbeaten record of 24, 13 of which have gone the distance.
