Groups E and F will be resolved at the World Cup in Qatar later.
Belgium need a win over Croatia in Group F to survive - while Morocco just require a draw against eliminated Canada.
Those matches start at 3pm.
Belgium manager Roberto Martinez knows it will be a tall order against a Croatian team that has lost just 1 of their last 18 matches.
At 7 o'clock, Germany take on Costa Rica in Group E, knowing they must win and hope that Spain get a positive result against Japan in the other Group game.
History will be made in the Germany - Costa Rica game as 38 year old Stephanie Frappart from France becomes the first woman to referee a men's game at a World Cup finals.
She has previously officiated a Champions League game and says she feels "a lot of pride" ahead of the occasion.
