'For me not to play all 18 holes, that was as frustrated as I've been in a long time,' Woods said. 'It is sore. I haven't had any treatment. As soon as I get back to Orlando I will.'
Woods said he plans to have an MRI to see where the neck stiffness is coming from. He did say that the injury began nagging him two weeks before the Masters.
'As I kept playing and practicing it never got better,' Woods said.
