The Confederation of African Football has changed venues of the quarter final clash between Equatorial Guinea and Tunisia from Ebebiyin stadium to the Bata stadium. The match is to be played on Saturday at 16:00 GMT.
Also, Sunday's quarter final game between Group c winners and Group D runners-up, has moved from Mongomo to Malabo. The match kicks off at 16:00, which means the remaining quarter final, also taking place in Malabo, has been pushed back to start at 19:30.
The Confederation of African Football said in a statement "the two pitches (in Ebebiyin and Monogo) have been adversely affected by combination of wear and tear from the six games played or to be played in each of them and the unstable weather conditions seen lately".
It added: "The eight teams qualified for the quarter-final stages onwards should be given the opportunity to play on grounds that provide the highest standards, specifically those of Bata and Malabo, to ensure the quality of play remains at the highest possible level."
