Wood is expected to be out at least four weeks with a partial tear in his right rotator cuff. The Cubs' right-hander underwent an arthrogram at Northwest Memorial Hospital on Friday, revealing the tear. Treatment options include conservative treatment or possible arthroscopic surgery on his shoulder, but a final decision hasn't been made on which to pursue. "My gut feeling is saying no surgery and strengthen it," Wood said. "I've still got to get more opinions."
