Midfielder Nosa Igiebor suffered a cut on his right palm as the Nigeria team bus was attacked by irate Ethiopia fans after Sunday's 2-1 win by Nigeria.
The Nigeria bus was delayed from leaving the stadium, and when they eventually did, the waiting fans hurled missiles at the bus, shattering the rear window.
The Betis midfielder was hit on the hand by a big stone, giving him a big slash with serious bleeding which needed immediate attention of team doctor Ibrahim Gyaran.
NFF General Secretary Musa Amadu explained that the incident forced the players to miss the dinner organized in their honour by the Nigerian embassy in Ethiopia.
"Their bus was stoned, and a player was injured," Amadu told the gathering. "As a result, the players do not feel safe enough to come out from their hotel."
NFF Vice President, Chief Mike Umeh, said the matter has been reported to the FIFA Security team at the match venue and he hopes action will be taken.
The matter was also reported to the Ethiopian Police by Eagles Chief security Officer, ACP Baba Abubakar.
