Ireland have been struck by another blow after it was confirmed that lock Paul O'Connell will miss Saturday's international clash with South Africa.
O'Connell returned to training at the start of this week and took a full part in the squad sessions held at Carton House on Monday and Tuesday.
However, the Munster second-row suffered a reaction and will not be fit for selection for this weekend's game against the Springboks.
Veteran O'Connell will see a specialist in the coming days and an update will be issued by the Irish Rugby Football Union in due course.
Ireland will name their squad on Thursday.
