Country singer Randy Travis is listed in critical condition after being admitted to a Texas hospital on Sunday. According to his rep, the crooner is suffering from complications of viral cardiomyopathy, a weakening of the heart muscle that is caused by a virus.

No other information has been given. An identical statement was posted to the singer's website later Monday.

Travis appears to be dealing with a fast-moving virus. On his website, the singer has a full slate of tour dates throughout the U.S. and Canada beginning July 10 and extending until late October.

After a series of personal setbacks in 2012 that included two alcohol-related arrests, Travis has focused on music this year, having collaborated with the Nashville Symphony in March, the Avett Brothers in April and releasing a new single, the George Jones tribute "Tonight I'm Playin' Possum," to acclaim in June.

The North Carolina native, 54, burst upon the scene in 1986, and quickly became one of the hottest country performers of his day, inspiring a generation with his back-to-basics traditional style. Albums such as his debut disc, 1986's "Storms of Life" helped to make him a superstar in the latter part of the 1980s and a frequent award show favorite. In all he has released over 20 studio albums.

His string of No. 1 tracks include "Forever and Ever, Amen," "Honky Tonk Moon," and "Too Gone Too Long." His latest chart-topper came in 2002 with "Three Wooden Crosses."
