Cubs pitcher Yu Darvish underwent arthroscopic surgery Wednesday to remove debris from his right pitching elbow.
Darvish, who was shut down three weeks ago after being diagnosed with a stress reaction on the top of his elbow, is expected to be ready for spring training.
The surgery was performed by Rangers doctor Keith Meister after a second opinion by Dr. James Andrews.
"He's had some issues all year," manager Joe Maddon said. "The conclusion is he needed this procedure."
Darvish hasn't pitched since May 20 because of elbow issues. He was 1-3 with a 4.95 ERA in eight starts in the first year of a six-year, $126 million contract.
