Barry Ferguson suspects if Celtic and Rangers do not return to the traditional derby ticket allocations they risk upsetting Sky Sports.
Away fans will return to the derby for the first time 2019 when the Glasgow rivals collide at Ibrox on April 3 - but only 700 Celtic supporters will be allowed in.
Rangers managing director Stewart Robertson earlier this year said a return to the 7000+ visiting crowd was not likely any time in the near future.
