Rangers failed their second serious examination of the promotion race as Jason Cummings' double inspired Hibernian to a 3-1 win at Ibrox, yesterday.
The Ibrox side have already been beaten at home by Hearts but lost further ground on the Scottish Championship leaders as they surrendered three first-half goals to Alan Stubbs' side.
Cummings put Hibs ahead after 26 minutes, making the most of Arnold Peralta's failure to deal with a meat-and-drink long ball.
Hibs full-back David Gray then climbed above Stevie Smith to head home the second on 31 minutes before Cummings finished off a clever counter attack to put the Leith side three up just before the break.
Rangers would need to show their fighting spirit if they were to get back into the match but the only aggression came from defender Bilel Mohsni as he seemed to get into a heated argument with a group of his own fans as he made his way up the tunnel at half-time. Nicky Law did pull one back for the hosts with a well-placed volley 10 minutes into the second-half but the home side just never looked capable of pulling off a remarkable escape.
Ally McCoist has overseen a list of underwhelming performances during his four-year reign and many will now ask if he is the man to take the club back to the top flight given his side now trail Hearts by six points after just seven games.
Hibs, however, will hope the win will reignite their promotion push as they rise five places to fifth.
