A message posted to his personal Twitter account states, "Tyler is seeking immediate care and has been advised by his doctors that he cannot travel or perform at this time."
Later, the note seems to downplay the severity of the medical issues affecting Tyler. It reads, "Steven is expected to make a full recovery. With proper rest and treatment he will be back on his feet soon rocking the world."
Tyler himself writes, "I'm very sorry and feel like I've let you down... I am not in a life threatening condition, but I need to deal with this right away... I promise I'll be back."
