Cyclist Lance Armstrong will make a "limited confession" to using performance-enhancing substances in his upcoming interview with Oprah Winfrey, the Associated Press reported on Saturday.

The admission, which would reportedly also include an apology, would follow a decade of staunch denials by the seven-time Tour De France winner that he ever cheated during his career.

The interview is scheduled to be taped on Monday and aired on Thursday on Winfrey's OWN network. Armstrong told the AP via text message that there would be no subjects off limits.

"I told her (Winfrey) to go wherever she wants and I'll answer the questions directly, honestly and candidly," he said. "That's all I can say."

Earlier this week, the head of the U.S. Anti-Doping Agency, Travis Tygart, revealed that a representative of the cyclist attempted to donate around $250,000 to the organization.

"I was stunned," Tygart told CBS News. "It was a clear conflict of interest for USADA. We had no hesitation in rejecting that offer."

Armstrong's attorney, Tim Herman, denied Tygart's allegation, saying he never made such an attempt.

The cyclist's career was effectively erased in August 2012, when both the USADA, with the backing of the International Cycling Union, stripped him of his championships and banned him from ever competing again.
