Van Halen have been forced to postpone four reunion shows because guitarist Eddie Van Halen “is undergoing a battery of comprehensive medical tests”.

Shows in Dallas, Cincinnati, Raleigh and Baltimore, which were due to take place this week, have now been moved to April.

A statement on the band’s website said that Eddie Van Halen's physician was working “to determine a defined diagnosis and recommended medical procedures.”

Fans have been told to keep hold of their tickets for the rescheduled dates or request a refund from their original point of purchase.

The long-awaited reunion shows were postponed last year after Eddie Van Halen was admitted into rehab.

As previously reported, the reformed Van Halen does not include original bass player Michael Anthony.
