Whitesnake will no longer be able to join The Scorpions on their upcoming US and Canadian tour

Whitesnake @ Seneca Niagara Events Center (Inside the Seneca Niagara Casino) Niagara Falls, NY 5-18-19
It is with profound disappointment and a heavy heart that I must announce that Whitesnake will no longer be able to join The Scorpions on their US and Canadian tour due to my continued treatment for a persistent upper respiratory infection that affects my ability to perform. This includes the cancellation of our own headlining shows as well.
While Whitesnake will no longer be on the tour, the Scorpions will be continuing on. We Wish Our Good Friends, The Scorpions Every Success!!!
We Wish You Well”
