Watch highlights of Rangers' 1-0 win over Falkirk in the Scottish Championship.

Billy King came off the bench to hand Rangers a vital debut goal as the Championship leaders scrambled to a narrow win.

The 21-year-old Hearts winger made a surprise six-month loan switch to Ibrox this week and celebrated the move with a stoppage-time diving header to hand his new side the points.

Gers looked like they were heading for their first blank under Mark Warburton but King's intervention means they now move eight points clear of nearest rivals Hibernian, who were busy beating St Johnstone in the League Cup semi-finals.

It was a cruel blow for Peter Houston's disciplined Bairns, whose title hopes appear to be over having now fallen 10 points behind the table-toppers.
