The band made a vague announcement on their website on Tuesday that reads "Due to personal issues, Richie Sambora will not be performing on this upcoming leg. All shows will go on as scheduled." The leg is currently making its way across Canada and will play a number of shows in the U.S. before concluding on April 25th in San Jose, CA.
This isn't the first time Sambora has missed a tour with the band. In April of 2011 the guitarist checked into rehab for exhaustion and alcohol issues and was forced to miss that year's North American tour. The next leg of the world tour will kick off on May 7th in Cape Town, South Africa and will travel across Europe before concluding on July 05th at London's Hyde Park.
