A publicist for country star George Jones is knocking down a rumor that he is suffering from pneumonia.

Kirt Webster said Friday night that Jones remains hospitalized in Nashville with an upper respiratory infection. He is receiving antibiotics and doctors expect him to stay until Tuesday. The 80-year-old singer was admitted Thursday.

Jones released a statement saying "thanks to all my fans and friends for their prayers and support during this time."

The Saratoga, Texas, native is known for several classic country hits, including "White Lightning" and "He Stopped Loving Her Today."
