The IRFU has revealed that a player in the Ireland squad has potentially tested positive for Covid-19, one day before the All Blacks game.
The player is to undergo further testing to ascertain if this is a false positive.
The entire Irish squad and management are now undergoing PCR and lateral flow testing.
The lateral flow testing produced no positives and the PCR test results are expected later today.
Ireland are due to take on New Zealand at the Aviva Stadium at 3.15pm on Saturday.
