JUPITER, Florida (AP) - Dustin Johnson has undergone surgery to repair cartilage in his right knee. He is expected to be out of competition until sometime in January.
Johnson won The Barclays in August to become the first player since Tiger Woods in 1999 to win in each of his first four years on the PGA Tour straight out of college. He has five career wins.
His agent, David Winkle at Hambric Sports, said Tuesday that Johnson has been feeling pain since July, when he was a runner-up to Darren Clarke in the British Open. Johnson is expected to be crutches for a week, then resume chipping and putting. He should be at full speed by the end of December before returning to golf.
It was not clear if he would be able to play the Tournament of Champions at Kapalua, which starts Jan. 6.
