Dr. Conrad Murray May Ask to Delay Preliminary Hearing

Dr. Conrad Murray's legal team claims it may not be ready for the preliminary hearing setting next month, because they still have not received the full criminal file on the Michael Jackson manslaughter case.

Miranda Sevcik, spokesperson for Murray's lawyer, Ed Chernoff, tells TMZ they have only received 3,500 pages of discovery.  Sevcik cites a news report in which the D.A.'s office claims it has "hundreds of thousands of pages of material." 

But a D.A. spokesperson told TMZ on Friday that the statement that there were "hundreds of thousands" of pages was their error ... and in fact there are only  "thousands of pages" and the defense has received "the bulk of it."

Sevcik's response ... "It's odd. It seems like an awfully big miscalculation."  

Sevcik says if the defense team does not get all the docs soon, they may ask to delay the preliminary hearing setting -- set for June 14.
