A rock and roller is taking a break from the road.

FOX's Jacquelyn Karl reports:

Singer Steven Tyler of Aerosmith doesn't want to miss concerts, but he has to for medical reasons that haven't been revealed.

Tyler writes in a statement, "Please don't worry, I am not in a life threatening condition." The front-man adding he needs to "deal with this immediately" so he can go on to do future performances.

It does mean Aerosmith has to cancel its last four concerts on the South America tour in Brazil, Chile, Argentina and Mexico. Tyler promises he'll be back.
