The teammate is not identified in court documents, but he is referred to as having played with Tejada on the Oakland Athletics. Tejada won the 2002 American League Most Valuable Player award while playing for the Athletics and is a five-time All-Star. He now plays for the Houston Astros.

The documents indicate that a plea agreement has been reached with Tejada. The court papers were filed a day after superstar Alex Rodriguez acknowledged past use of performance-enhancing drugs. The New York Yankees third baseman does not face charges.

The FBI also is investigating whether Roger Clemens, a seven-time Cy Young winner, lied to Congress last year when he denied using steroids or human growth hormone. Clemens and Rodriguez top a list of big name, drug-tainted stars, including Barry Bonds, Mark McGwire and Jose Canseco, whose actions cast doubt on their on-field accomplishments.

Tejada faces as much as a year in jail if convicted on the misdemeanor charge of making misrepresentations to Congress. Under federal guidelines, the Dominican Republic player would probably receive a lighter sentence.

The charge came in a legal document called a "criminal information," which only can be filed with the defendant's consent and typically signals a plea deal.

Messages left for his attorney, Mark Tuohey, were not immediately returned.

Tejada is charged with lying to investigators for the House Committee on Oversight and Government Reform in 2005. Congressional staffers did not place Tejada under oath when they questioned him, but they advised him "of the importance of providing truthful answers," according to the court papers.

During the interview, Tejada denied knowledge of an ex-teammate's use of performance-enhancing drugs.

Tejada "unlawfully withheld pertinent information from the committee because defendant Tejada, before and during his interview with the committee staff, then and there well knew that player #1, one of his teammates on the Oakland Athletics, had used steroids and HGH," the papers state.

The court papers filed by Assistant U.S. Attorney Steven Durham charge that during spring training in 2003, Tejada had purchased a substance believed to be HGH from the player, giving him payments of $3,100 and $3,200.

In the Mitchell Report on doping in MLB, Oakland outfielder Adam Piatt is cited saying he discussed steroid use with Tejada and having provided Tejada with testosterone and human growth hormone.

The Mitchell Report, issued in December 2007, also included copies of checks allegedly written by Tejada to Piatt in March 2003 for $3,100 and $3,200 - the same payment amounts in Tuesday's court filing.

Tejada came under scrutiny after another ex-teammate, Baltimore Orioles' Rafael Palmeiro, testified before the House committee in March 2005. Later that year, Palmeiro was suspended by MLB after testing positive for a steroid. Palmeiro said his positive test must have resulted from a B-12 vitamin injection given to him by Tejada. That prompted Congress to talk to Tejada.
