GUNS N’ ROSES singer Axl Rose has broken a bone in his foot, requiring a surgical procedure to insert a plate and screws. Rose revealed the injury via Twitter, saying “This is what can happen when you do something you haven’t done in nearly over 23 years,” apparently referring to GN’R‘s surprise concert last Friday featuring three members of the band’s classic lineup: Rose, guitarist Slash and bassist Duff McKagan. He also posted a video interview with his orthopedic surgeon in which the foot specialist revealed that Rose is currently in a cast and cannot put any weight on his foot. She pinpointed the break at Rose‘s fifth metatarsal.

Tonight’s (Friday, April 8) GN’R show in Las Vegas will go on as planned, according to a statement issued by the band’s publicist. Rose will wear a cast, and will apparently have a special stage setup that will allow him to perform. “He’s having a set, I think, designed for the stage,” the foot specialist said, “so he can perform for everyone still.” She also confirmed that Rose will have to limit the amount of weight he puts on the front part of his foot “for about four weeks — and then we will let him gradually progress from there.”

GUNS N’ ROSES will play two shows in Vegas this weekend. The band will also play two gigs in Mexico City in addition to two Coachella festival dates, before launching a stadium trek this summer.

Several hours after announcing the tour on April 1, GUNS N’ ROSES played a gig at the Troubadour, one of the Los Angeles clubs where the band first performed before the release of its debut album, 1987’s “Appetite For Destruction”.

The concert was advertised as “Not In This Lifetime” by the venue, quoting what Rose said in 2012 about a possible classic GUNS N’ ROSES lineup reunion. The same phrase has since been announced as the name of the band’s upcoming tour.
