I thought he got married and didn't want to spend time on the road. I suppose it could be argued that he might be around and about during home tournaments, but if Andy has a new physio, that's who we will see. The new guy is supposed to be a back specialist, and has had back surgery himself, so I'm not sure where Andy Ireland would fit in.
Andy's new physio is
also a back specialist who has, or had, his own Harley Street practice (so not cheap then), although I can't for the life of me remember his name now.
As for Andy Ireland, in Jonathan Overend's Wimbledon report (wonderful to read all that again!) he says "A thought also for former physio Andy Ireland, who cut down on his work with Murray this year for personal reasons." I seem to recall too that Andy I was married and said he didn't want to go on travelling round the world, either that or Mrs I put her foot down, but whichever, I'm sure his departure from team was amicable, since there could be a whole host of reasons why he wasn't present at Wimbledon. Our Andy did take Tim Henman's former physio on board for a while, but obviously it makes sense to now have a physio who is also a fully qualified back specialist.
