Ian Gavan/Getty ImagesJoe Jackson, father of the late Michael Jackson, has been hospitalized, according to a report.

The patriarch of the Jackson family went in for a routine check-up on Friday when the appointment took a turn for the worse, TMZ says.

A source tells the site that Joe was scheduled for some tests with his personal doctor when he became weak with a high fever. According to the report, his doctor admitted Joe to the hospital and he’s been there ever since.

Jackson, 87, is still running a high fever and so far doctors have not been able to pinpoint the exact issue.
