In April 2013, Hetson stopped touring with Bad Religion, supposedly due to divorce, and after briefly playing as a four-piece band, Bad Religion recruited Mike Dimkich of The Cult to fill in for Hetson. At that time, bassist Jay Bentley released the following statement: "Greg Hetson is dealing with some personal issues, if he wishes to make a statement we will support that, if he chooses not to we will support that. Mike Dimkich is indeed helping us out right now, and we are genuinely appreciative. Right now we are just looking forward and getting ready to play our shows.
Some days ago, Jay Bentley has confirmed on The Bad Religion Page that Dimkich is an official member of Bad Religion ("Dimkich is a permanent member of the band"), meaning that Hetson is no longer a member of the band.
