Sometime after he won the British, he suffered from vertigo. He had a hard time with that, then he got married and priorities for him changed (according to him). While trying to come back, he's had to deal with the yipps.
He has shot a couple of low 60s rounds in the last few years, but hasn't been able to put much together. Most of his exemptions run through this year, so he'll need to make cuts this year to stay on tour.
With that said, I don't think we'll see much of him after the next couple of years.
