According to Blabbermouth.net California thrash metal veterans Slayer have released the following "open letter" to their "fans around the world":
"Slayer fans everywhere — it's time to let you know what is going on with our brother Jeff Hanneman [guitar].
"As you know, Jeff was bitten by a spider more than a year ago, but what you may not have known was that for a couple of days after he went to the ER, things were touch-and-go. There was talk that he might have to have his arm amputated, and we didn't know if he was going to pull through at all. He was in a medically-induced coma for a few days and had several operations to remove the dead and dying tissue from his arm. So, understand, he was in really, really bad shape. It's been about a year since he got out of the hospital, and since then, he had to learn to walk again, he's had several painful skin grafts, he's been in rehab doing exercises to regain the strength in his arm; but best of all, he's been playing guitar. We were all excited when he joined us onstage for the encore a year ago at the "Big Four" show at Coachella. Since then, we've given him all the time and support he's needed to continue his rehab so he can come back to the band fully recovered and able to deliver the kind of shows we all want him to.
"While Jeff's been doing some writing and has been coming to rehearsal over the past several weeks, he has decided he needs to take more time to continue his rehab. While we want him back onstage with the band, all of us support his decision. So, we're very grateful that Gary Holt [Exodus] will continue to fill in for Jeff, and will tour with us until Jeff completes his rehab and is ready to return. How long will that be? The best and most honest answer we can give you is "as long as it takes." We also wanted you to know that we've been doing some writing and recording for the next Slayer album — we've tracked a few songs, and will finish the album when we're off the road later this year. Gary will join us on tour in Europe and the U.K. in May and June, and then we'll all see you on this summer's [Rockstar Energy Drink] Mayhem Festival
In a fall 2011 interview with U.K.'s Classic Rock magazine, Hanneman said that was kicking back in a hot tub with a couple of beers when noticed a spider bite him on the arm.
"Didn't even feel it," he said. "But an hour later, I knew that I was ill." On his way to the hospital, "I could see the flesh corrupting," he recalled. "The arm was real hot. I got to the emergency room, and thank god the nurse knew straight away what it was. By chance, although it's pretty rare, she had seen a case a little while before. At that point, I was an hour away from death."
Although the spider bite itself was not serious, it had caused bacterial infection in the deeper layers of the skin and tissues of the arm.
"Unbelievably, the doctor was a Slayer fan," said Hanneman, "First thing he said to me was: "First I am going to save your life. Then I am going to save your arm. Then I am going to save your career.'"
Hanneman underwent emergency surgery to remove the dead and dying tissue. The doctor was able to save the muscles and the tendons, but the guitarist had a large open wound on his arm. He spent the next two months in hospital, having extensive skin grafts and heavy doses of antibiotics to suppress the infection.
"I had to learn to walk again," Hanneman said: "I hadn't stood up for a month, apart from anything else. The skin grafts were very painful and all the muscles and tendons in the arm where very weak. That was OK, though. I count myself lucky that the nurse and doctor knew right away what had happened to me, because things could have been a whole lot worse."
