LOS ANGELES – Ukrainian cyclist Yaroslav Popovych, a former teammate of Lance Armstrong, has been subpoenaed to testify before a grand jury that is probing doping in the sport, his lawyer said.

Attorney Ken Miller said Popovych will appear before the federal panel Wednesday in Los Angeles, but gave no further details.

The 30-year-old Ukrainian cyclist has been a rider on three Armstrong teams since 2005, when they both rode for Discovery Channel.

Federal prosecutors have called several associates of Armstrong, a seven-time Tour de France champion, in recent weeks.

Allen Lim, an exercise physiologist for Lance Armstrong’s Team Radioshack, appeared before the Grand Jury, as did Stephanie McIlvain, a long-time friend of Armstrong.

McIlvain’s lawyer said she told jurors she never heard Armstrong admit taking banned performance-enhancing substances.

Investigators have been interviewing witnesses and collecting evidence in their probe of whether or not Armstrong and other pro cyclists took banned substances.

Testimony is kept secret and sessions are closed to reporters.

Armstrong has repeatedly denied all allegations that he ever took any sort of banned performance-enhancing substances.
