WASHINGTON — Jose Canseco's appearance before the grand jury investigating Roger Clemens is now scheduled for June 3.

Canseco will testify before the panel that will decide whether to indict Clemens for lying under oath to Congress.

Canseco was originally scheduled to testify in April, then it was pushed back to May. His lawyer, Andrew Kirsh, said scheduling issues forced another postponement to June.

The grand jury is reviewing Clemens' testimony before a congressional committee in 2008, when the seven-time Cy Young Award winner denied using steroids or human growth hormone.

Canseco has previously claimed he introduced several players to performance-enhancing drugs, but the retired slugger has said he has no knowledge of Clemens using them.
