The auctioneers say it was used by the laboratory that tested Reagan's blood when he was hospitalized after a 1981 assassination attempt in Washington. Bidding for the vial had passed the 7,000 pound ($11,000) mark Tuesday May 22, 2012. (AP Photo/PFCAuctions)

Aerosmith singer Steven Tyler will undergo surgery this week for an undisclosed medical condition, forcing the band to cancel the remaining dates of its North American tour.

The band's publicist, Marcee Rondan, said Tuesday that Tyler was "doing fine" but declined to elaborate on his condition.

"Despite Aerosmith's desire to keep the tour going as long as possible, Tyler's doctors advised him not to continue performing to give his voice time to recover," Rondan said in a statement.

Tyler, who turns 58 on Sunday, can't perform for an extended period of time, Rondan said, adding the band was on hiatus.

Aerosmith canceled recent concerts in Manchester, N.H., Pensacola, Fla., and Lexington, Ky., because of illness, though the tour press director did not disclose who was sick or the nature of the illness.
