Dennen provided these details to fans, "As some of you may know I've been very sick for the past two weeks. On March 6th I came down with severe strep throat, which subsided and as soon as that happened turned into bronchitis and laryngitis.

"As I continued to push myself to keep touring and playing these shows I've damaged myself very badly. I am a Type One juvenile diabetic which means my immune system is extremely poor, so I quickly picked up more illnesses.

"After visiting an urgent care clinic in Dallas the recommendation was to go to an ENT and my actual doctor to get blood work done. As of now I still have no voice and feel like absolute death, so I took the suggestion and unfortunately had to fly home.

"What this means is I will not be able to perform for the rest of the Ashes To Ashes tour, and that breaks my heart. Fortunately enough I have amazing friends who are willing to fill in for me until I recover, so please I urge you to still come see Sworn In on the rest of this tour while I work on recovering. Thank you all for understanding, and I will see you all soon."

He later reassured fans that the band plans to move forward with their headline tour which kicks off on March 29th. He wrote, "Tyler here again. just to make it clear our headlining tour is NOT cancelled. I am only missing the ashes to ashes tour to ensure that I will be healthy enough to play these headlining sets. don't worry. I'll see you all soon."
