Steven Tyler will be stepping away from the stage for some time after his latest show left him severely injured.

According to a statement from Tyler’s team, his band, Aerosmith, was performing a concert in Long Island when he injured himself while singing.

Immediately after performing, Tyler flew to Boston to meet with his ENT doctor, who x-rayed the singer’s vocal cords and found them to be “mangled,” TMZ reports.

It’s believed Steven Tyler’s vocal cords suffered the injury early on in his show but he was able to power through his set. In fact, he hid it so well that audience members had no idea he was in pain.

A source told TMZ, that Tyler can’t even speak at the moment; only “squeaks” come out. His ENT doc has put him on at least 30 days of vocal rest.

In his statement, Tyler wrote, “To all our fans, ‘I’m heartbroken to say I have received strict doctor’s orders not to sing for the next thirty days. I sustained vocal cord damage during Saturday’s show that led to subsequent bleeding. We’ll need to postpone a few dates so that we can come back and give you the performance you deserve.”

While there is not much more information than that, a source told TMZ that “Steven is an animal. There’s no stopping him.” Hopefully, that means Tyler will be back better than ever as soon as he takes care of himself.
