The Nigerian Football Federation has temporarily suspended all further matches within its top professional league after a lack of medical facilities at one ground led to the death of a player.
Nasarawa United defender Chineme Martins, 22, collapsed after ESPN reported he collided with a player from opposing club Katsina United during their match in the town of Lafia.
With limited medical personnel on scene, club officials, teammates and fans attempted to revive him before the only ambulance available to take him to a local hospital failed to start, according to BBC Sport.
While the Nasarawa club won the match 3-0, their players broke down in tears after hearing of Martins' death after the full time whistle had blown in an incredibly emotional scene.
