Muse and My Chemical Romance have been forced to axe another tour date due to the ongoing food poisoning problem.
The two bands are on a joint tour across the US and have already been forced to cancel two shows after band members and their crew became violently ill after a show in Virginia at the end of April.
In addition to the Pennsylvania and Ohio gigs, the bands will now also not be playing at the Civic Centre in Portland, Maine this coming Sunday (May 13).
My Chemical Romance did perform at the Bamboozle Festival in New Jersey at the weekend, but according to a statement, the show put them in a further weakened state. They have now been ordered to rest by doctors.
