A federal judge has delayed the court hearing of Barry Bonds' personal trainer until Friday.
Greg Anderson was initially scheduled to appear before U.S. District Judge Susan Illston on Wednesday and say whether he intends to testify at Bonds' perjury trial.
Attorney Mark Geragos asked for the hearing to be delayed because another trial he is doing in Southern California is running longer than expected.
Bonds' trial is scheduled to start next week.
Anderson has said previously through Geragos that he will refuse to testify.
Anderson has already spent a year in prison for refusing to testify before a grand jury about his relationship with Bonds.
The judge has barred prosecutors from using key evidence including positive steroids tests unless Anderson testifies.
