BOSTON -- New England Patriots star Tom Brady had offseason surgery, the quarterback said at a golf tournament in Miami Beach.

Brady, 28, told reporters yesterday at the tournament that he had surgery last week, joking that he had to take it easy on hard swings.

It was not immediately clear what the surgery involved. The Patriots confirmed that Brady had an operation but declined to share details.

Brady did not play in the NFL Pro Bowl on Feb. 12. He was at the Super Bowl on Feb. 5 in Detroit, where he conducted the opening coin toss.
