Steven Tyler is recovering after suffering a seizure in Brazil, according to a source close to the Boston Globe.
Tyler himself has not acknowledged what exactly happened this week, although he did confirm that four upcoming shows would be cancelled due to a medical issue he described as "not life-threatening."
"To everybody in South America ... I'm very sorry and feel like I've let you down," Tyler said in a statement. “I flew back to the U.S. on doctor’s orders last night after the show in São Paulo. Please not to worry … I am not in a life threatening condition, but I need to deal with this right away, and get some rest and medical care immediately in order to sustain and maintain my future performances."
The 69-year-old rocker continued, "I promise I'll be back. Unfortunately, health does not wait and it’s something even I can’t schedule around our shows. As they say, ‘We humans make plans, and God laughs.’ I love you all and will be back with you soon."
A statement from Aerosmith said Tyler is expected to make a full recovery and will soon be "back on his feet rocking the world."
The band has suffered a few health complications in recent years, including in 2016, when guitarist JOe Perry collapsed backstage due to dehydration and exhaustion.
