Dustin Johnson had surgery on his left knee Thursday, but the procedure shouldn't hinder his plan to be healthy for the start of the PGA Tour.
Earlier today, Dustin Johnson underwent arthroscopic surgery to repair cartilage damage in his left knee.

Johnson's agent, David Winkle, said the surgery was minor and that Johnson needed some cartilage cleaned up around his knee.
It "is considered routine and similar in nature to his prior right knee surgery in December of 2011,'' Winkler said (via ESPN).
Johnson, 35, hadn't indicated he was feeling any discomfort in his knee. He held the No. 1 spot in the world for a while, but struggled in the second half of the 2018-19 season.
He went eight consecutive tournaments without a top-15 finish, which marks his longest slump. He now is No. 3 in the world rankings.
