London Irish and Scotland centre Joe Ansbro is recovering in hospital after suffering a broken neck against Munster on Friday night.
Ansbro sustained the injury during a pre-season tour match and remains at University Hospital, Cork. He will return to the UK later this week.
"Joe broke a small bone at the top of his neck early in the game's second half," read a statement released by London Irish.
"After An MRI scan, it was confirmed that immediate surgery was not required, and the injury would be managed by external fixation."
While London Irish have yet to set a date for Ansbro's return, Scotland team doctor James Robson expects him to resume playing in around three months.
Robson's prognosis means the 26-year-old will miss the autumn internationals against New Zealand, South Africa and Tonga.
"The management of the injury Joe has sustained typically involves a period of between six and eight weeks' immobilisation," Robson said.
"After that there will be a further four to six weeks of rehabilitation before he can look at a return to the game. We wish Joe well in his recovery."
