Bennington is under doctor’s orders to refrain from physical activities or traveling.

Affected shows are October 12 in Shanghai, China; October 15 in Wuhan, China;October 17 in Taipei, Taiwan; October 19 in Beijing and October 21 in Macau, China.

The concerts were organized as fundraisers to benefit Sichuan, an area ravaged by a devastating earthquake this past May.

Thanks to donations from concert promoter Emma Ticketmaster and Linkin Park, funds will still be contributed to the band’s nonprofit organization, Music for Relief, and matched by the World Bank.

The funds will benefit post-earthquake reconstruction projects in the Sichuan Province initiated by Chinese Civil Society Organizations.

The band apologized to fans for the cancellations in a message on their web site.

Tickets will be refunded at point of purchase.
