Undated (AP) _ NEWARK, N.J. (AP) - The United States Boxing Association withdrew cruiserweight championship recognition Thursday from Stanley Ross, who tested positive for a drug after winning the title from Boone Pultz on a split decision Dec. 7 in Washington.

Pultz once again is champion.

Bob Lee, USBA president, said following Ross' split victory over Pultz that Ross tested positive for marijuana.

A boxer's post-fight urine sample is divided into two parts. One part is tested and the other is frozen.

If the first part of the sample proves positive, the second part also is tested. The second test also proved positive, Lee said.

''We're calling the fight a no-decision and the title reverts back to the man who originally had it,'' Lee said.

Lee said Ross would be dropped from the USBA rankings. Any further disciplinary action against him would have to be taken by the Washington, D.C., Boxing Commission, he said.

Ross, of Miami, was one of 39 boxers suspended by the New Jersey Athletic Commission last August for testing positive for drugs.

On Sept. 25, the suspension against Ross was lifted after officials failed to prove legally that the sample tested was his.
