TRENTON, N.J. (AP) -- Guitarist Richie Sambora will not be performing with Bon Jovi during the current leg of the band's Because We Can tour.
The band, on its website, cited "personal issues." The band says all shows will go on as scheduled. No other information was given.
Hours before the announcement late Tuesday, Sambora tweeted that he was "Watching more of the 'Every Road Leads Home To You' cover videos." That was a reference to a fan contest promoting a song on his solo album "Aftermath of the Lowdown."
The 53-year-old has struggled with substance abuse. He has done several stints in rehab.
Bon Jovi is slated to perform in Edmonton, Canada, on Wednesday and the current leg of the tour is scheduled to end April 25 in San Jose, Calif.
Bon Jovi's 12th album, "What About Now," debuted at No. 1 on the Billboard 200 albums chart last month.
