Twenty-six college football players who tested positive for marijuana or cocaine use at a scouting camp in January were selected in Tuesday's NFL draft, according to published reports.

Two of the players were picked in the first round and four in the second. None was identified.

Although many clubs had said they would not draft any of the 57 who reportedly tested positive, the 26 were chosen by 16 clubs, The New York Times and Boston Globe reported yesterday.

Teams that reportedly picked the players were Denver, the New York Giants, Cincinnati, Dallas, Detroit, Green Bay, Houston, Kansas City, the Los Angeles Raiders, Miami, Minnesota, New Orleans, Philadelphia, St. Louis, San Diego and San Francisco.

Denver Coach Dan Reeves told the Denver Post that two of the Broncos' nine draftees had tested positive. "I'm not going to take one that I know for sure, that there's no question about a drug problem ," said Reeves, who in March said he would not select any of those tested positive. "But I'm not going to condemn a kid who may not be an abusive user ."

During a complete physical exam at camps conducted by NFL scouting combines, 355 players were tested. Results were distributed to all 28 NFL clubs . . .

Buster Rhymes, wide receiver for the Minnesota Vikings, has returned to the Hazelden Treatment Center for alcohol and drug abuse in Center City, Minn., apparently for treatment of drug problems.

The Vikings issued a statement that Rhymes, a highly rated rookie from Oklahoma last season, was being "treated for an illness." Rhymes spent four weeks at Hazelden in December and January . . .

Defensive end Fred Dean will retire from the San Francisco 49ers before the start of training camp in July, according to the San Francisco Chronicle.

Dean could not be reached for comment, the story said, but Coach Bill Walsh denied that the team would pay Dean, 34, to retire. Dean would earn a $125,000 bonus for reporting to training camp . . .

Navy running back Napoleon McCallum, drafted in the fourth round by the Los Angeles Raiders despite a five-year military commitment, said in a statement: "I'm very happy that I got drafted by the Raiders. I'm glad they had that much confidence in me." He said he hopes to spend his leaves practicing with the Raiders.
