King’s management told Pollstar that he is expected to resume his tour schedule January 30 in Fort Worth, Texas.

The 81-year-old bluesman, who had been scheduled to perform at the Grand Opera House on Thursday night, was admitted to The University of Texas Medical Branch at Galveston, said Paul McCarthy, a nurse administrator.

King had a low fever but was resting comfortably, hospital spokesman John Coloen said Friday. He said he had no information on the ailment for which King was being treated, but he and McCarthy said King was expected to be discharged later Friday or Saturday.

King has a history of diabetes.

Messages left early Friday with King’s management agency, Lieberman Management LLC of New York, were not immediately returned.

With his trademark guitar that he named “Lucille,” King spent much of 2006 on the road and has concerts booked in September, 2007.

Born on a plantation in Itta Bena, Miss., King started out on street corners playing for pocket change, according to his Web site. He went on to become one of the nation’s most influential blues musicians.

In December, President Bush awarded King the Presidential Medal of Freedom for his musical contributions.
