The Super Falcons overnight fell by the odd goal to hosts Mexico at the invitational Revolution Cup in Leon.
Both teams are preparing for the FIFA Women’s World Cup in Australia and New Zealand in July.
It was the Super Falcons sixth straight loss under American coach Randy Waldrum.
The Nigerian ladies dominated the first 20 minutes of this game, but could not put away the chances they created.
Kiana Palacios headed in a cross, firing a first-time shot into the net in the 85th minute for the only goal of the game.
Spain-based forward Rasheedat Ajibade captained the Nigerians with Barcelona star Asisat Oshoala conspicuously absent.
France-based goalkeeper Chiamaka Nnadozie impressed again to ensure the Super Falcons did not suffer a heavy defeat.
The Falcons will next face Colombia Saturday in continuation of the tournament.
I think Nigeria should withdraw from the world cup. This team is terrible and cannot be relied upon to compete favourably. We are just going there to make up the numbers
