He will not be performing for the rest of the tour.
Five Finger Death Punch have released a statement regarding frontman Ivan Moody.
At a recent show in Tilburg, Netherlands Ivan appeared to say, "This is my last show with Five Finger Death Punch", although the band stated he hadn't left the band.
They've now announced that Ivan will not be continuing on with the rest of their tour, with Tommy Vext, the vocalist from Bad Wolves filling in.
Ivan released a statement saying, "I am embarrassed and ashamed to admit that I have fallen off the wagon again.
"I was on shaky ground prior to our performance in Tilburg, and although a lot of the events of that show were out of my control, the shame of not delivering pushed me over the edge.
"It would not be fair to my bandmates or my fans to continue to perform in my current condition. One of the worst parts of addiction is the loneliness you feel, so having the support of my band and all the knuckleheads is what drives me.
"I am committed to getting better so I can get back out on stage as soon as possible."
Guitarist Zoltan Bathory added, "As a band, we are committed to supporting Ivan's road to recovery.
"We are as baffled and saddened as anyone to watch our brother continue to struggle. Almost everyone in the world knows someone who struggles with addiction, and can relate to how the self-destruction of someone they care about is very difficult to watch.
"Five Finger Death Punch has every intention of playing the dates we’re committed to and beyond. The band is bigger than any one member."
The band have also announced a tour for later this year with In Flames and Of Mice & Men...
