The American world number 25, broke the table when he sat on it following a practice session at the Thailand Open.
The United States Tennis Association (USTA) said he is expected to be out of action for up to six weeks, effectively ending his season.
Californian Querrey, 21, who was seeded third for the ATP Tour event, said on his Twitter feed: "Worst day ever."
He had enjoyed a good season prior to the accident, winning the Los Angeles Open in August and reaching the ATP Hall of Fame Championship final in Rhode Island in July
