NEW YORK -- Disgraced former world record holder Tim Montgomery said he took testosterone and human growth hormone before the Sydney Olympics, and does not deserve the gold medal he won in the 400-meter relay.

The admission was made during an interview scheduled to air Tuesday night on HBO's "Real Sports with Bryant Gumbel."

"I have a gold medal that I'm sitting on that I didn't get with my own ability," Montgomery said in the interview. "I'm not here to take away from anybody else's accomplishments, only my own. And I must say, I apologize to the other people that was on the relay team if that was to happen."

Montgomery never tested positive for drugs, but he was banned from track for two years and his world record in the 100 was erased after he was linked to the BALCO investigation. He retired after the ban was imposed in 2005.
