The Ghanaian players and staff were pelted with water bottles from the stands as they left the pitch at the Moshood Abiola National Stadium, and Nigeria supporters then invaded the pitch.

The crowd had overturned and damaged two dugouts before tear gas was used and police hit out at fans with batons.

Fifa told BBC Sport Africa it is analysing official match reports, and will then decide if action will be taken against the NFF.

"The relevant information included in the match reports will be evaluated by the competent disciplinary bodies before deciding on the next steps to be taken," a Fifa statement added.

Meanwhile, a doping officer on duty at the match died after suffering a suspected cardiac arrest after full-time.

Attempts to resuscitate Dr Joseph Kabungo failed, and the Zambian official was pronounced dead after arriving at a hospital in Abuja.

"We mourn the passing of our Caf [Confederation of African Football] and Fifa medical officer Dr Joseph Kabungo and we extend our sincere condolences to Dr Kabungo's family and the football family at large," Football Association of Zambia president Andrew Kamanga said.

"He was a dedicated and widely loved member of our football community and his impact was vast, having also been part of the 2012 Africa Cup of Nations winning team."

An NFF statement said Dr Kabungo was found "gasping for breath near the dressing room of the Ghanaian team" while on his way to find a Ghana player for a doping test.

Fifa added its deepest condolences to Dr Kabungo's family and loved ones, as well as to the Zambian football community.
