In early 2011, Hanneman was diagnosed with [[necrotizing fasciitis]]. According to the band, doctors said that it likely originated from a spider bite. Araya said of Hanneman's condition: "Jeff was seriously ill. Jeff ended up contracting a bacteria that ate away his flesh on his arm, so they cut open his arm, from his wrist to his shoulder, and they did a [[Skin grafting|skin graft]] on him, they cleaned up ... It was a flesh-eating virus, so he was really, really bad. So we'll wait for him to get better, and when he's a hundred percent, he's gonna come out and join us."<ref>{{cite web|url=http://www.roadrunnerrecords.com/blabbermouth.net/news.aspx?mode=Article&newsitemID=164324 |title=Slayer Working On New Material |publisher=Roadrunnerrecords.com |access-date=April 6, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20111209154304/http://www.roadrunnerrecords.com/blabbermouth.net/news.aspx?mode=Article&newsitemID=164324 |archive-date=December 9, 2011 }}</ref> The band decided to play their upcoming tour dates without Hanneman.<ref>{{cite news|url=http://www.roadrunnerrecords.com/blabbermouth.net/news.aspx?mode=Article&newsitemID=153855 |title=Slayer's Hanneman Contracts Acute Infection; Band To Bring In Guest Guitarist |work=Blabbermouth |url-status=dead |archive-url=https://web.archive.org/web/20110216083103/http://www.roadrunnerrecords.com/blabbermouth.net/news.aspx?mode=Article&newsitemID=153855 |archive-date=February 16, 2011 }}</ref> [[Gary Holt (musician)|Gary Holt]] of [[Exodus (band)|Exodus]] was announced as Hanneman's temporary replacement.<ref name="blab-garyholt">{{cite web|url=http://www.roadrunnerrecords.com/blabbermouth.net/news.aspx?mode=Article&newsitemID=154012 |title=Slayer Recruits Exodus Guitarist Gary Holt For Upcoming Tour |date=February 15, 2011 |access-date=July 12, 2014 |url-status=dead |archive-url=https://web.archive.org/web/20110318065941/http://www.roadrunnerrecords.com/blabbermouth.net/news.aspx?mode=Article&newsitemID=154012 |archive-date=March 18, 2011 }}</ref> [[Cannibal Corpse]] guitarist [[Pat O'Brien (guitarist)|Pat O'Brien]] filled in for Holt during a tour in Europe.<ref name="slayer1">{{cite web|url=http://www.slayer.net/us/news/cannibal-corpses-pat-obrien-will-step-slayers-guest-guitarist|archive-url=https://web.archive.org/web/20110723041827/http://www.slayer.net/us/news/cannibal-corpses-pat-obrien-will-step-slayers-guest-guitarist|archive-date=2011-07-23|title=Cannibal Corpse'S Pat O'Brien Will Step In As Slayer'S Guest Guitarist &#124; The Official Slayer Site|work=The Official Slayer Site |publisher=Slayer.net|date=May 19, 2011|access-date=July 1, 2011}}</ref> On April 23, 2011, at the American Big 4 show in [[Indio, California]], Hanneman rejoined his bandmates to play the final two songs of their set, "South of Heaven" and "Angel of Death".
