Steven Tyler will take a sabbatical from performing after sustaining serious injuries during his most recent concert.

According to a statement from Tyler’s team, he injured himself while singing during an Aerosmith concert in Long Island.

Tyler visited his ENT doctor in Boston after his performance, who performed an x-ray on the singer’s vocal chords and found that they were “mangled,” according to TMZ.

Steven Tyler managed to continue his set despite what is believed to have been vocal cord damage early in the performance. He really managed to hide his agony so well that others were unaware of it.

A source claims that Tyler is presently unable to speak at all; just “squeaks” can be heard. For at least 30 days, voice rest has been recommended by his ENT doctor.

Tyler said in his statement, “To all of our fans, ‘I’m sad to report I have gotten serious doctor’s instructions not to sing for the next thirty days. I hurt my voice chords during the concert on Saturday, which led to further bleeding. A few of our concerts will need to be rescheduled so that we can give you the entertainment you deserve when we return.

Although there aren’t any other specifics, a source told TMZ that “Steven is a beast. He is unstoppable. That hopefully means Tyler will come back stronger than before after he takes care of himself.
