Linkin Park have been forced to scrap a concert in Washington, D.C. on Thursday (10Feb11) to allow frontman Chester Bennington to recover from a mystery illness.
The Crawling hitmakers cancelled their Verizon Center gig after the singer was ordered to rest.
A statement posted on the rockers' website reads: "Lead vocalist Chester Bennington is ill and under doctor's orders to refrain from performing.
"The band sincerely regrets this unavoidable cancellation and apologises to fans for any disappointment caused."
As WENN went to press, Linkin Park's next tour stop in Uncasville, Connecticut on Friday (11Feb11) was still scheduled to go ahead as planned.
