LOS ANGELES (AP) -- Aerosmith front man Steven Tyler says he has entered a rehab clinic to treat an addiction to pain killers he has taken to cope with 10 years of performance injuries.

Tyler says in a statement released Tuesday to People and Rolling Stone magazines that he is eager to return to work with his bandmates.

The band canceled a summer tour in August after Tyler fell off the stage during a performance in South Dakota and broke his left shoulder.

Tyler's doctor Brian McKeon told People that orthopedic injuries over the past decade have left the 61-year-old rocker with severe chronic pain that will require surgeries on his knees and feet.

A message left by The Associated Press after business hours for Tyler's manager Allen Kovac was not immediately returned.
