Based on doctors' recommendations, Bon Jovi's concerts at Madison Square Garden on Friday and Saturday will be rescheduled to next week.
The postponement is due to the bronchitis that frontman Jon Bon Jovi has been fighting since last Saturday.
"The decision was difficult to make, but made in the interest of delivering the full, powerhouse performance for which Bon Jovi is known," a band spokesperson said Thursday.
Tickets purchased for Friday's show will be honored on April 13, and Saturday's tickets will be honored on April 15.
