Brighton's Women's Continental League Cup match at Charlton Athletic has been postponed after a Seagulls staff member tested positive for coronavirus, and the club say Sunday's top-flight match against Aston Villa is also in doubt.
Wednesday's postponement came after wind damage saw Everton and Manchester United's game also called off earlier.
Everton said there were "safety concerns" at Walton Hall Park.
The Toffees lost 3-1 to Manchester City in the Women's FA Cup final on Sunday.
The Merseyside outfit said they "expect the fixture to be rearranged", as both they and the Red Devils bid for their first points in Group C.
Brighton's announcement came just before kick-off and they added that the unnamed individual who has tested positive does not have any symptoms and will self-isolate.
