Celtic and Rangers will not admit away fans to the final two Premiership games between the sides this season.
The Glasgow giants are set to clash at Celtic Park on April 8, with a return game at Ibrox to take place after the league split but only home supporters will be attendance at either game.
The decision comes after discussions between the clubs, with agreement that the move is necessary for security and supporter safety.
The third game between the sides in the coming weeks, the Scottish Cup semi-final, is unaffected, with an even allocation of tickets at Hampden Park guaranteed.
A substantial away support had been tradition at Old Firm derbies until recent years.
Last year, plans were in place for away fans to be barred from the first two derbies of the season but that decision was later reversed. Instead, games taking place since then have seen the number of opposition fans kept to around 800 fans.
