The trial of Michael Jackson's doctor Conrad Murray will resume on Wednesday.
Los Angeles Judge Michael Pastor ordered the delay so defence lawyers can get more details on test results that the coroner's office recently conducted. The tests dealt with the levels of the sedative lorazepam that were found in Jackson's body.
Murray's lawyers have raised the issue of lorazepam levels and told jurors that the amounts were so high they could have put several people to sleep.
Deputy District Attorney David Walgren told Judge Pastor that he asked for the coroner's office to re-test for lorazepam levels and found that they were lower than the defence analysis suggested.
Murray has pleaded not guilty to involuntary manslaughter.
