(Reuters) - The Turkish Super Lig will assign foreign Video Assistant Referees (VARs) for crucial games until the end of the season, the Turkish Football Federation (TFF) said on Friday.

The Super Lig has been marked by violence and controversial refereeing decisions in recent months, with a referee punched in the face in December by a club president, while Fenerbahce have also raised concerns about bias in a tight title race.
