Jon Bon Jovi used his band's brief break from its current overseas tour to undergo knee surgery in Dublin, Ireland, to repair a torn MCL he suffered during a rainy show in Helsinki, Finland, on June 17.

Prior to the surgery, JBJ talked to 'Extra' about the injury. "It was raining; we were outside," explained the singer. "It was nothing that abrupt … it just sort of gave out and tore. Fortunately, we have a week off. So the doctor claims I'll be alright for Istanbul eight days later."

A Twitter post Friday (July 1) from JBJ's brother Matt Bonjiovi revealed the surgery was a success: "Jon's knee surgery went great. All is well -- it'll take a lot more than that to slow him down. Next stop Istanbul!"

In that same 'Extra' interview, JBJ also talked about the health of Bon Jovi guitarist Richie Sambora, who recently returned to the band after a stint in rehab.

"It's always good to have Richie at my side," said Jon. "He's doing great. There's dark clouds in everybody's worlds and he came through them. He's doing well. He's happy, he's healthy and he's focused."

As mentioned, Bon Jovi's overseas tour resumes July 8 in Istanbul, Turkey. The trek is scheduled to run through a July 31 gig in Lisbon, Portugal.
