Alex Rodriguez's upcoming hip surgery and the injury accompanying it had nothing to do with his past use of steroids, according to his doctor.

Dr. Bryan Kelly described a patient whose left hip muscles had "just shut down," becoming so weak that A-Rod had trouble doing a simple leg raise during exams.

After seeing medical imaging of the hip, Kelly stated he had "no doubt" Rodriguez's humiliating playoff meltdown was caused by the injury.

"I was more surprised that he was able to play at all with a hip that looked like that," Kelly said. "Most people would not be able to play with a hip function like this and the imaging that looked like his."
