Aerosmith singer Steven Tyler will undergo a surgery this week for an undisclosed medical condition, forcing the band to cancel the remaining dates of their North American tour. The band's publicist, Marcee Rondan said on 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 that the band was "on hiatus."

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