Update: Aerosmith will play The Gorge on Aug. 16 after all.

As of Thursday morning, Aerosmith had reportedly canceled their Saturday show at the Gorge Amphitheatre because drummer Joey Kramer was dealing with heart issues. The band also canceled Wednesday night's Concord, Calif. show.

But a Thursday night Live Nation news release says the show is still on and tickets are still on sale.

According to the celebrity gossip site TMZ, a source close to the band said that the 64-year-old Kramer has had heart issues in the past and that he was planning to undergo heart surgery.

"The band regrets not being able to perform for their fans," a message on Aerosmith's Facebook page said Thursday. The posting also directed those who were planning to attend the 'Let Rock Rule' tour show to receive their refunds at the point of purchase.

Aerosmith are currently touring with Slash with dates scheduled into September.
