Coach Andy Robinson named his final squad last week for the two-Test tour, starting on June 12, but now faces an injury crisis with Murray’s fellow prop Jon Welsh having also pulled out with a leg injury.

Murray picked up ankle injuries whilst playing for Northampton Saints and having been assessed by Scotland team doctor, James Robson, has been forced to withdraw.

“Following consultation between our medical team and the medics at Euan’s club, Northampton, the decision has been taken in the interests of the player for Euan to undergo a period of rest, treatment and rehabilitation for differing injuries affecting both ankles,” said Robson.

The 29-year-old’s absence has opened the door for Edinburgh number three Geoff Cross.

Cross, with just two caps to his name, is called up from the Scotland A squad who play the IRB Nations Cup in Romania the same time as the first-team travel to Argentina, leaving resources very stretched.
