Randy Travis is still in critical condition following emergency surgery last week. "[He] has been under heavy sedation since he came out of surgery late Wednesday night and is resting comfortably," Travis' publicist Kirt Webster said in a statement. Travis, 54, underwent a procedure to relieve pressure on the brain at the Heart Hospital Baylor Plano, located north of Dallas. He had been admitted to hospital last week for a heart condition caused by a virus. Travis has received an outpouring of support from his fellow country musicians and fans.
