"I missed the ITM Cup with a bulge in my neck that jammed up one of my nerves, so it was touch and go whether I would need surgery," he said after the Maori All Blacks' first training session on Sunday.
"It's not like an ankle where you can keep on strapping it. There's definitely a danger involved with playing when your neck is not 100 per cent."
The 29-year-old has been a Super Rugby regular since debuting for the Blues in 2008. He has played for the Crusaders and more recently the Highlanders under Jamie Joseph and said getting a clear scan was a big relief for him.
"It's turned out a lot better than it could have, so I'm stoked, especially because I could be part of this tour. Playing for the Maori is special. It's definitely something about the environment and the team itself."
To be able to add to his nine caps for the Maori, and to tour with some good mates on the team and coaching staff, including mentor Joseph, is a bonus.
All three of the Ngapuhi players in the team were part of the Highlanders this year.
"Elliot Dixon and Kurt Baker were both down here and Elliot came up north with me at the end of the Super season for a week because his family is from around Waimamaku and he comes up every now and then to visit," Murray said.
The laid-back Murray isn't too worried about being without a Super Rugby or even an ITM Cup contract and believes the tour could open up opportunities. He couldn't have asked for a better way to get back into rugby and is looking forward to the tour.
The 26-strong squad left for England on Tuesday for a three-match tour with matches against Leicester Tigers on November 13, an RFU Championship XV six days later, and Canada in England at Oxford University on November 23.
