49ers’ Montana Undergoes Surgery on His Right Shoulder

Joe Montana, the quarterback who has led the San Francisco 49ers to a pair of Super Bowl titles, underwent shoulder surgery two weeks ago, it was learned Thursday.

“He’s rehabilitating well, and everything is right on schedule,” Dr. Michael F. Dillingham told the San Mateo Times. “We think he should be ready to throw in two or three weeks, but nothing is 100%.”

The surgery was performed at a Redwood City hospital, and Montana has been doing rehabilitation work at a sports medicine clinic in the area, the doctor said. The team has made no announcement on the subject. Training camp opens July 20.

Dillingham said he performed arthroscopic surgery on Montana soon after the quarterback participated in a 49er mini-camp.

“He had persistent pain in the shoulder when he was throwing,” Dillingham said. “We scoped his (right) shoulder and cleaned out a small piece of cartilage.”

Dillingham said Montana probably suffered the injury in the 49ers’ last game, the Dec. 29 playoff loss to the New York Giants. The quarterback’s right shoulder was bruised during the game.
