A season that began with Tiger Woods celebrating a fifth Masters title ended with a fifth surgery on his left knee.

This one wasn’t serious.

Woods said Tuesday on Twitter he had arthroscopic surgery last week to repair what he described as minor cartilage damage. In a statement Woods released on social media, Dr. Vern Cooley said he looked at the rest of the knee and found no additional problems.

“I’m walking now and hope to resume practice in the next few weeks,” Woods said, adding that he looked forward to traveling to Japan in October for a planned Skins Game exhibition and the ZoZo Championship on Oct. 24-27.

Mark Steinberg, his agent at Excel Sports, described the knee as little more than “irritating.”

“It was bothering him, but arthroscopic these days is different than we had years and years ago,” Steinberg said. “He’s up and walking now. This will have no effect on the fall or winter.”

Woods has a light schedule the rest of the year — Japan in late October, his Hero World Challenge in the Bahamas the first week of December and then the Presidents Cup.
