The joint Jimmy Page-Black Crowes tour won't be taking flight anytime soon, as the Led Zeppelin guitarist continues to suffer from back problems that may require surgery.

According to representatives for the tour, Page injured his back in early August, just as he and the Black Crowes had begun the second leg of their North American tour in support of the "Live At The Greek" double album (see [article id="1425892"]"Page-Crowes Tour Postponed; Chris Robinson Engaged"[/article]).

Canceled dates from that leg had been incorporated into the upcoming tour's itinerary, an outing that was scheduled to kick off on September 15 in Mountain View, California.

Page has been ordered to rest for the next six weeks, after which time the guitarist will be re-examined by doctors to determine if surgery is needed to alleviate the injury.

In addition to canceling their own North American and European tour plans, Page and the Black Crowes have

also been forced to nix plans for a four-night co-headlining stint with The Who at Madison Square Garden in New York City set for early October.

Tour organizers are holding out hope, however, that Page and the Crowes might be able to make up the New York City concerts for sometime in December, if Page is able to fully recover in time.

If and when Page is able to continue touring, you can count on the Black Crowes to flock to his side when needed, frontman Chris Robinson explained to MTV News prior to the tour's launch earlier this year.

Since getting its retail release in July, Page and the Crowes' "Live At The Greek" album
