LaVonna Martin, last year's 100 meter hurdles U.S. champion, Monday was suspended for two years for a doping violation by The Athletics Congress.

TAC also suspended 400 meter specialist Jon Copeland of Seton Hall for three months for doping. Martin and Copeland waived their rights to appeal. Martin applied for early re-instatement and her coach, Tatiana Zelentsova, faces possible disciplinary action by TAC.Martin, of Dayton, Ohio, tested positive Jan. 23 for furosemide, a banned diuretic. The test was part of TAC's out-of-competition program.

On April 9 in Columbus, Ohio, Martin told a Drug Hearing Board panel she unknowingly took the banned drug. She said Zelentsova gave her tablets containing furomeside without telling her what they were. Zelentsova admitted to the panel she knew the tablets contained the banned substance but told Martin they did not.

"Unfortunately," the panel's written decision notes, "we may not consider the fact that Ms. Martin did not intend to violate TAC's doping rules, even given the face that the diuretic was given to her without her knowledge."

Martin is suspended through Jan. 22, 1993 but the panel's report suggests an application of reinstatement by Martin and recommends disciplinary action against the coach.

Martin, 24, was the top-ranked American 100 meter hurdler last year and ranked sixth in the world.

Copeland ran the lead leg for Seton Hall's victories 4x400 meter relay team Feb. 22 at the U.S. Indoor Championships at New York. He tested positive at that meet for phenylpropanolomine and for pseudoephedrine in an amount greater than 10 micograms per milliliter. Both are banned stimulants.

Copeland waived his right to appeal when he did not request a review of the findings against him within the alloted 28-day period after notification. His suspension began Feb. 22 and runs through May 21.

Because of Copeland's test, Seton Hall lost its relay victory and Shore Athletic Club was boosted from second place to first. The victory put Shore in sole possession of third place in the men's team standings with 11 points. Seton Hall had tied for fifth, but lost all its points because of Copeland's violation.
