Tiger Woods has withdrawn from the Genesis Open and the Honda Classic because of a back injury.
"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 on his website.
"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."
Woods, who had planned to play four times in a five week stretch leading up to the Masters, pulled out before his second round at the Dubai Desert Classic last week because of back trouble.
Agent Mark Steinberg said at the time the 14-time major champion has suffered a back spasm that hindered his golf swing.
