NASHVILLE (AP) - Country star George Jones has been hospitalized. Jones postponed weekend concerts in Atlanta and Salem, Va., after doctors admitted him to a Nashville hospital on Thursday.

A news release says Jones had a fever and irregular blood pressure during a routine checkup.

The 82-year-old singer, considered one of the genre's greatest singers, is in the midst of a yearlong goodbye tour that wraps up in November in Nashville. He has occasionally canceled or postponed shows in the last year because of health issues.
