Rangers defender Connor Goldson has been the target of racist abuse following the Europa League aggregate win over Red Star Belgrade.
Goldson was a key member of the backline at the Marakana as Gio van Bronckhorst's side sealed a spot in the quarter-final stage.
The 29-year-old was involved in a post-match row with the Red Star players as the home side reacted angrily to the post-match celebrations.
