The Leeds Rhinos clinched a 24-0 win over the Huddersfield Giants, who are unable to name a team for Sunday’s Women’s Super League match.
The match between St Helens and Wakefield had already been canceled because Wakefield could not field a team.
“A combination of Covid-19 and breeding problems” contributed to the decision according to St Helens.
The reasons given did not meet the criteria for requesting a referral under the Covid Fixture protocols.
It comes after two women’s Super League games were moved from Sunday to Monday due to a lack of medical staff.
Huddersfield v Castleford and Warrington v York have both been postponed with the latter taking place on Tuesday, while the Giants game with the Tigers has been rearranged for the end of the season.
Trinity played Bradford at Oddsal on Monday and suffered a heavy 46-6 defeat, with Danielle Bose scoring four tries for the hosts.
