The Black Keys have canceled the upcoming North American leg of their International Players Tour, with dates for the jaunt abruptly erased without explanation from the band’s social media pages and official website.

On Friday, fans noticed that the Ticketmaster listing for the International Players Tour’s North American arena shows — which was set to begin September 17 in Tulsa, Oklahoma and run through November 12 in Detroit — listed all of the shows as canceled.

Venues’ individual listings for the concerts — including a September 18 gig at Austin’s Moody Center and an October 30 show at New York’s Madison Square Garden — also updated the pages to acknowledge that the shows had been canceled and that fans would automatically receive refunds. “Unfortunately, the Event Organizer has had to cancel this event,” the Moody Center’s listing noted.

The Black Keys’ official website has also scrubbed all of the band’s upcoming tour dates except for a single one-off show, a July 6 gig at Chicago’s NASCAR Street Race. 

The duo of Dan Auerbach and Patrick Carney, who just completed a European leg in support of their new album Ohio Players, have not issued a statement regarding the cancelations. A rep for the band did not respond to Rolling Stone’s request for comment at press time.

The cancellation does not appear to be health-related, as the Black Keys just performed on the season finale of The Voice earlier this week.
