Stoppage time strike is big moment for David Gray and disaster for Rangers bossAlready a dark cloud hangs over the Derek McInnes reign at Rangers after his competitive Ibrox debut went badly awry.Any sense of anticipation over the 54-year-old rejuvenating this club dissipated when Hibs substitute Callum Wright’s effort trundled into the net three minutes into stoppage time. This 2-1 win is big for Hibs but for Rangers, they are already five points adrift of Premiership leaders and defending champions Celtic.Nothing is decided after two matches, of course not. There are 36 still to play but Rangers are playing catch-up with their title rivals.
