Sean O'Brien set for at least eight weeks on the sidelines while Leinster confirm Leavy suffered neck strain
Leinster have confirmed that Sean O'Brien will be sidelined for between eight and 12 weeks after having surgery on his broken forearm.
O'Brien picked up the injury playing for Ireland against Argentina and now faces a race against time to be fit for the 2019 Six Nations campaign. The province also revealed that it was a neck issue that kept openside flanker Dan Leavy out of Saturday's historic win over the All Blacks. Ireland head coach Joe Schmidt had previously said that it was 'full body soreness' that saw Leavy sit out training.
A fitness update was also issued on Robbie Henshaw, with the centre ruled out for four to six weeks after straining his hamstring in the warm-up against Argentina.
Summer signing Joe Tomane is a long-term absentee, with the Wallabies international not set to return from a hamstring injury for five months.
