Cameroon were forced to a 0-0 draw by Ethiopia in an African Nations Championship Group B clash at the Stade Huye on Thursday.
Cameroon sought to score but they failed to break down a resolute Ethiopian side.
With this result, Cameroon now have four points and are second in Group B.
The Indomitable Lions need at least a draw in their last Group game against already qualified Democratic Republic of Congo.
For Ethiopia, they must beat Angola and hope DR Congo do them a favour by defeating Cameroon.
