Officials confirmed for Switzerland vs Algeria
The game is set to kick off at 8pm local time (4am UK time) at BC Place in Vancouver, with the winners going on to face either Colombia or Ghana at the same venue in the round of 16.
Viewers in the UK can watch the game on BBC One, with coverage set to begin ten minutes before kick-off.
The referee for this one is Argentina's Yael Falcon.
This is the 37 year old's third game of the competition in his first World Cup.
He has taken charge of two absolute walkover so far: Sweden's 5-1 win over Tunisia, and Mexico's 3-0 victory over the Czech Republic.
Falcon has so far proved willing to keep his cards in his pocket, showing just one yellow in each of his two games so far.
Running the lines for Falcon is the very agreeable Masimiliano Del Yesso and the rather eloquent Facundo Rodriguez.
Two Peruvians will be on hand in the ground in the shape of fourth official Kevin Ortega and reserve official Michael Orue.
It's another Argentinian in charge of the VAR booth, with Hernan Mastrangelo heading up the decisions on the replays.
Mexico's Erick Miranda and Chilean Juan Lara will offer support.
