Sambora tweeted Friday that although he is doing fine, he will not continue the tour, The Hollywood Reporter said.
"Thanks 4 your notes & concerns. I'm doing [expletive] great," he tweeted. "This is a private matter but please know I love the band and you fans!"
The guitarist has been absent from the band's North American tour due to "personal reasons," but rumors have pointed to a monetary dispute as the core problem. However, lead man Jon Bon Jovi insists Sambora is still a part of the band.
"All I can say honest to God is that it's a personal matter, but we love him very much," Bon Jovi said on the Ellen DeGeneres Show in April. "He's absolutely still a member of the band."
