Early Third Division pace-setters East Fife have added two more players to their squad.
Fox is an Under-20 international
Scotland Under-20 goalkeeper Scott Fox has joined on loan from Celtic, while midfielder Gary Greenhill has been signed from Berwick Rangers.
Former Dunfermline youngster Greenhill, 22, has been purchased for an undisclosed fee, having scored one goal already this season.
The loan deal for Fox will last the entire season.
The goalkeeper played in Scotland final game at this summer's Under-20 World Cup and performed well in the 2-1 defeat to Costa Rica.
