The rocker was hospitalised after a frightening accident on 17 September (15), which left him with injuries including broken bones, a lacerated liver and concussion.

The 48 year old is expected to make a full recovery, but he has pulled out of an upcoming tour with his other band The Dead Daisies.

Fortus says in a statement, "On September 17, 2015, I was involved in a motorcycle accident. As a result, I broke my shoulder blade, collar bone, six ribs, a toe, I have a bruised lung, lacerated liver and a concussion. Amazingly, my doctors have assured me that I will make a full recovery. I have never missed a show in my entire career, and, unfortunately, I will have to miss the entire Australian and New Zealand leg of this tour.

"I am devastated that I will not be able to play... (But) I am healing quickly and getting stronger by the day."

The musician hopes to be well enough to rejoin The Dead Daisies for an upcoming gig with Kiss on the annual Kiss Kruise, which sets sail from Florida next month (Oct15).

No more details about the accident have been given.
