Five days before Michael Jackson died, his manager called the singer's doctor and said Jackson was sick.

A voicemail from the manager was played Thursday for a Los Angeles jury in the lawsuit by Jackson's mother against the concert promoter who was then arranging his "This Is It" tour.

On the voicemail message, Frank Deleo told Dr. Conrad Murray that Jackson has had an "episode" and suggested that blood tests be done on him.

There was no further elaboration on what the episode was and a lawyer for Katherine Jackson didn't ask further questions about it.

Also on Thursday, police Detective Orlando Martinez is in a second day of testimony about his investigation of Jackson's June 25, 2009, death from an overdose of propofol.
