The brothers Jonas have postponed their May 17 shows at Arena Monterrey in Mexico “due to health concerns around the country resulting from the outbreak of the H1N1 flu.”

The afternoon and evening shows have been moved to July 31. Tickets for the original shows will be honored for the new date and any fans who are unable to attend the rescheduled gigs can get a refund from the venue box office.

Tickets purchased during presale may have a different refund process, so fans holding them should contact customer service at JonasBrothersFanClub.com for details.

Fans who submitted for meet & greets will still be on the list for the new date, with those who cannot attend the rescheduled show advised to also contact the site’s customer service.

All kidding aside, the band posted a message on their fan club site citing concern for the safety of their fans as the reason for the postponement.

“Although the situation is stabilizing, Jonas Brothers and Live Nation do not want to cause parents and families any concern over their children attending the concerts. Many fans are traveling great distances to see and experience a Jonas Brothers concert for the first time and we want them to have the best and safest time possible. Jonas Brothers have been overwhelmed by the reception of their many fans in Mexico. They very much look forward to performing their first-ever shows in Monterrey on July 31, 2009.”
