Ireland flanker Sean O'Brien now looks like a major doubt for next weekend's visit of the All Blacks after he was taken off during the first-half of Ireland's match with Argentina on Saturday.
O'Brien was pulled ashore for Leinster teammate Dan Leavy just before half-time holding onto his right forearm.
The Argentina match was O'Brien's first game for the national team since last year's 28-19 win over the Pumas in Dublin but the two-time British & Irish Lions tourist could now be set for another stint on the sidelines after his latest setback.

O'Brien's injury was compounded by the loss of Robbie Henshaw during the warm-up with the Leinster centre a late scratch for Ulster centre Will Addison.
Henshaw looked crestfallen as he hobbled from the pitch, 15 minutes before kick-off, and the IRFU later confirmed he was pulled from action as a precaution for "tightness" in his hamstring.
Henshaw missed out on the trip to play Italy in Chicago but did play a full 80 in the Gunness PRO14 win over Treviso on October 17.
