Rangers manager Ally McCoist says no decision has been taken on trialist Matias Abelairas.
The 26-year-old Argentinian midfielder is a free agent and holds an Italian passport, which means there is no need for the club to seek a work permit.
"He is looking fine," said McCoist. "He played in a close-doors game against Kilmarnock on Tuesday and he did fine.
"He is enjoying training and we are enjoying having him and that's the way we will keep it going at the moment."
Abelairas was previously with River Plate, but pursued the club for unpaid wages after being released.
He scored 11 goals in 89 appearances for the club during his seven years in Buenos Aires.
