Rugby Union: Ireland's O'Brien in doubt for Six Nations
DUBLIN (AFP) - Ireland flanker Sean O'Brien could miss the Six Nations championship after suffering a dislocated shoulder which requires surgery, his club Leinster confirmed on Monday, Dec 30, 2013.
O'Brien, who made his British and Irish Lions debut in the second Test against Australia in June, injured himself during Saturday's inter-provincial clash against Ulster.
The 26-year-old was forced off after 53 minutes in the tie which Leinster won.
"Sean is to have surgery this week to repair a dislocated shoulder, which will unfortunately keep him on the sidelines for several months," the club said on their website.
