The world number one and four time champion golfer Tiger Woods will miss the Masters after having surgery on a pinched nerve in his back. The American professional missed his usual warm up, the Arnold Palmer Invitational, because of back spasms. Woods, who will be absent from the Masters for the first time in 19 years, won his maiden Augusta title in 1997 and also claimed the Green Jacket in 2001, 2002 and 2005.
