Sidney Wood was declared winner of the title by default over Frank Shields in capturing the gentlemen's singles tennis title at the 1931 Wimbledon Championships. Shields withdrew due to a knee injury sustained during his semi-final match against Jean Borotra.[1] This made Wood the only player in the title's history to win without having to compete in the final.[2] Bill Tilden was the defending champion, but did not compete.
