Van Halen has postponed its April 7 concert at the Bradley Center, the band announced on its Web site.

After postponing several dates last week in order for guitarist Eddie VanHalen to undergo tests for an undisclosed medical condition, the band announced a hiatus that will last until April 19.

A total of 17 shows were impacted. Van Halen, 53, has been treated for alcoholism and cancer in the past.

Fans are asked to keep tickets, which will be honored at a future date. For refunds, return tickets to place of purchase.
