3. In an April 1989 baseball game against the Toronto Blue Jays, Marty Barrett, a 2nd baseman for the Boston Red Sox, partially tore the anterior cruciate ligament (ACL) in his knee. Two days after the game, Barrett became a patient of Dr. Arthur Pappas, the doctor employed by the Red Sox, and Dr. Pappas performed surgery on Barrett at the University of Massachusetts Medical Center where Pappas was employed as a surgeon on the hospital's surgical staff. Barrett was scheduled to return to the team after a 3 month rehab but the day before he was to be activated from the Disabled List, Barrett noticed swelling in the knee and he consulted with Dr. Pappas about whether he should return to the team or continue his stay on the Disabled List to continue his rehabilitation. a.
