Italy and England's Six Nations games, which were due to be played over the weekend of March 14th, have been officially postponed.
They are the second group of fixtures which will have to be played at a later date due to the coronavirus outbreak in Italy.
Ireland and Italy's men's, women's and U20 games, which were scheduled to be played this weekend in Ireland, were all postponed last week.
The Italian government announced on Wednesday that all sporting events in the country must be played behind closed doors until April 3rd.
"Six Nations notes the decree issued by the Italian Government on March 4th with respect to all upcoming sporting events in that country," tournament organisers said in a statement.
"The decision has now been taken to postpone the three matches between Italy and England (Men’s, Women’s, and U20) set to take place over the weekend of 13th/14th/15th March, with the intention to reschedule them at later dates.
"Based on the information that is currently available, all other Six Nations matches are set to go ahead as scheduled. As previously stated, Six Nations fully intends to complete all 15 games across all three championships when time allows. We will refrain from making any rescheduling announcements while we keep assessing the situation.
"Six Nations will continue to monitor developments with our unions and their respective governments and health authorities. We remain fully supportive of any preventative measures taken in the interests of overall public health in relation to the Coronavirus and we will respect instructions provided by government authorities and health organisations."
