Aberdeen TV commentator Willie Garner believes the Dons were given a "different outcome" to Rangers on two identical incidents at Ibrox.
Saturday saw Jim Goodwin's side go down 1-0 to a later Kemar Roofe goal to make it no wins in 10 for the Dons across all competitions.
That run dates back to the Stephen Glass era but still leaves Aberdeen in 10th place in the Premiership with just eight wins all season.
