RANGERS stopper Rob Kiernan needed security protection at Ibrox on Saturday after coming under attack from a bitter mob of fans.

SunSport understands Kiernan — left out of Mark Warburton’s 18-man squad for the 1-1 draw against Ross County — was left shaken by the level of verbal abuse aimed at him from a number of supporters still angry over the midweek 4-1 hammering by Hearts.

Sources revealed he was targeted as he made his way to the players lounge at half-time.

It’s believed several stewards had to intervene to prevent the flashpoint escalating.

The defender was left out against the Staggies with Philippe Senderos coming in for only a third start of the season.

It’s expected Warburton will speak to the 26-year-old about the incident when the squad returns to training at Auchenhowie.

Kiernan — who cost a modest six-figure sum from Wigan in 2015 — signed a contract extension last July.

The ex-Kilmarnock loanee, who once worked with Warburton at Watford, has made 71 appearances for Gers.

It’s unclear yet if the scenes have made him reconsider his future.
