Rangers let slip a two-goal lead and lost 3-2 at Falkirk.
Rangers boss Mark Warburton has told Rangers TV that he stands by his substitutions in Friday's shock 3-2 defeat at Falkirk.
The Ibrox club seemed on course for an 11th Scottish Championship win in 12 outings when Kenny Miller and Barrie McKay fired them ahead inside 10 minutes.
However, Warburton's side were rocked when Blair Alston, Myles Hippolyte and Robert McHugh found the net in the last 17 minutes to condemn Rangers to their third league defeat of the campaign.
The ex-Brentford boss came under fire on Twitter for his decision to remove his two goalscorers for Harry Forrester and Nicky Clark prior to Falkirk's first goal, while Michael O'Halloran also replaced Billie King.
"Barrie and Kenny have worked so hard of late, and we weren’t putting on 16 and 17 year-old boys – we were putting on experienced players," he said to Rangers TV, quoted by the Glasgow Evening Times.
“The bench was a high quality bench, and we wanted to add that energy and maintain a tempo to it, so I have no problem with the substitutions. In the second half we weren’t good, but I don’t know how many corners we had in the second half, and how many chances we had, so we need to look at it and take the rewards when they are there.
“Someone said to me about negative substitutions we put out on Michael O’Halloran, Nicky Clark and Harry Forrester – I’m not sure how much more positive we can be."
Despite the defeat, it is highly unlikely that it will negatively affect Rangers' promotion bid this season.
As it stands, the Glasgow giants sit 11 points clear of second-placed Falkirk, with the luxury of a game in hand. Barring an epic capitulation, Warburton's boys will be plying their trade in the big time next term.
