The decision was made after consultation among PRO14 Rugby, Zebre and Ospreys after it was established that Ospreys could not be guaranteed that their flight to Italy would go ahead as scheduled due to the current severe weather affecting the UK, Ireland and Europe.
Additionally, freezing temperatures and further snowfall is expected in Parma today which would also put the fixture at risk.
Making a decision closer to kick-off would cause great inconvenience for all involved in the fixture and this action has been taken to ensure the health and safety of all the players, supporters, match officials and club staff.
Details about the rescheduled date will be confirmed as soon as possible.
All purchased tickets for the clash will remain valid for the rearranged fixture or can be refunded.
