Tiger Woods announced on Twitter that he will not be attending Genesis Open or the Honda Classic the following week due to back spasms. He also made a statement on his website.
"My doctors have advised me not to play the next two weeks, to continue my treatment and to let my back calm down," Woods said in a statement. "This is not what I was hoping for or expecting. I am extremely disappointed to miss the Genesis Open, a tournament that benefits my foundation, and The Honda Classic, my hometown event. I would like to thank Genesis for their support, and I know we will have an outstanding week."
