Nacional Asuncion's charge at the top of the Paraguay Division Profesional was put on hold, only by having their scheduled match postponed.
They were set to take on Deportivo Carapegua, but the fixture was put on hold.
Nacional still hold an eight-point buffer at the top of the table, and have a game in hand, after second side Libertad fell to Guarani 2-1 at home.
Guarani climbed to third spot on the back of the win, a point shy of their Sunday victims.
Cerro Porteno brought up their first win in three, with a 4-0 rout of Sol de America.
Rubio Nu earned just their second victory of the season to put some space between them and cellar-dwellers Sportivo Luqueno, with a 2-1 triumph away at Cerro Porteno PF.
Luqueno were denied away to Olimpia 4-3, while Deportivo Capiata were held at home by General Diaz 1-1.
