"It was what the doctor anticipated, reattachment of muscle to bone," Padres manager Bud Black said Friday. "The doctors expect a full recovery. He'll be ready to go by Spring Training.
The procedure was performed by Dr. Heinz Hoenecke and Dr. Lorenzo Pacelli at Scripps Clinic.
Stauffer was working his way back to the big leagues and was set to make his second rehab start with Triple-A Tucson earlier this month when he experienced soreness in his right shoulder. Stauffer then returned to San Diego to be reexamined.
Stauffer was in line to start on Opening Day until the final week of Spring Training, when he first started to feel discomfort in his elbow. He started the season on the disabled list, but he was activated on May 14 in time for a start in Washington.
Stauffer experienced soreness in his elbow -- in his flexor tendon bundle -- late in that outing against the Nationals. He allowed four runs (three earned) in five innings and eventually landed on the disabled list again on May 18.
Stauffer will likely be a non-tender candidate this winter. He made $3.2 million this season and was the sixth-highest paid player on the team behind Huston Street, Carlos Quentin, Orlando Hudson, Jason Bartlett and Chase Headley.
