CENTRE-back Gary MacKenzie has been ruled out until the new year as he prepares to have surgery on his hip.
The 26-year-old was last spotted in MK Dons’ 1-1 draw with Notts County at stadium:mk last month having made a brilliant start to the League 1 season.
But after a series of tests and scans, the defender – who had been called up to Craig Levein’s Scotland squad for the last round of 2014 World Cup qualifiers – will be sent for a hip arthroscopy, otherwise known as keyhole surgery.
Head of sports medicine Simon Crampton said: “Gary has had a problem within the hip joint that has been affecting his ability to perform to his high standards.
“Following a series of investigations and consultation with professor Ernest Schilders, a world-renowned hip specialist, the decision was made that the issue needs to be rectified surgically.
“Gary will undergo the operation next Monday and then will complete an intensive rehabilitation process with our medical team and it is expected that he will be sidelined for at least 12 weeks.
“Gary is a very strong and determined individual and I know he will be putting everything into his rehab.”
