The network, citing unidentified sources, says the U.S. Open winner will undergo knee surgery.
Update at 12 p.m. ET: Woods posted a statement on his website.
"While I am obviously disappointed to have to miss the remainder of the season, I have to do the right thing for my long-term health and look forward to returning to competitive golf when my doctors agree that my knee is sufficiently healthy," he says. "My doctors assure me with the proper rehabilitation and training, the knee will be strong and there will be no long-term effects."
