Brazil and Nigeria played a 1-1 draw in an international friendly match on Sunday.
Joe Aribo put Nigeria ahead in the first half but Casimero put Brazil back on level term after the break at the Singapore National Stadium.
Brazil was the dominant side but poor finishing denied the South Americans many chances.
Just as Brazil was settling nicely into the game, Neymar got injured and limped off the pitch after just 12 minutes of action. The injury appeared to be a hamstring, but a doctor's check will determine the real issue. He was replaced on the field by Philippe Coutinho.
A great chance came for Brazil in the 27th minute when Casemiro's pass met Gabriel Jesus, but the Manchester City player's header was saved by Francis Uzoho.
Three minutes later, a one-two play by Brazil was stopped by Uzoho as the ref sounded his whistle for water break.
But Nigeria took the lead after 35 minutes when Moses Simon penetrated Brazil's defence and found Joe Aribo who made his way past defenders and shot in.
Brazil kept the pressure but Nigeria held on to maintain their 1-0 lead into the break.
Three minutes after the restart, Casemiro scored to level up for Brazil after which Uzoho sustained an injury that looks bad, and was replaced with Maduka Okoye who is making his Nigeria debut.
Nigeria improved from their first-half performance and it was Samuel Chukwueze who posed more threat to the Brazilian defense.
However, none of the sides could change the score as the game ended 1-1 and the draw extended Brazil's winless run to four games.
