Henshaw out of Argentina tour
Hand surgery has denied Robbie Henshaw first refusal on Brian O'Driscoll's Ireland berth after the Connacht centre was ruled out of next month's tour of Argentina.
Irish rugby bosses have confirmed the highly-rated Henshaw exacerbated a hand problem in training this week, and will now miss the two-Test series against the Pumas.
The 20-year-old has been widely tipped to succeed the retired O'Driscoll in Ireland's midfield, but will now miss out on the first chance to stake a claim for the vacant 13 shirt.
A statement from the Irish Rugby Football Union read: "Robbie sustained the injury earlier in the season and it had not limited his ability to train or play.
"He exacerbated the injury in training this week and further specialist advice has recommended that surgical repair of the damaged ligaments should not be delayed further."
Ulster's Darren Cave will now be favourite to start at outside centre for Ireland's Tests against Argentina on June 7 in Resistencia and June 14 in Tucuman.
Ireland are yet to name a replacement for Henshaw, but losing the much-vaunted youngster will be a blow to head coach Joe Schmidt.
Former Leinster boss Schmidt will have viewed the summer tour as the ideal vehicle for blooding the next generation of centres as Ireland start the long build-up to the 2015 World Cup.
O'Driscoll has tipped Henshaw and Cave to lead the charge to replace him for Ireland's World Cup bid, but now Schmidt must do without his leading contender for the summer tour.
