Abner is set to return to Real Madrid this week.
The Brazilian wing-back has been playing on-loan in Portugal with Estoril this season.
However, A Bola says Abner is now set to cut short the deal and return to Madrid, where he's expected to join Castilla.
At Estoril, Abner managed ten league games and was left dissatisfied with his progress.
The 21 year-old is a Brazil U20 international.
