Dundee United sent Rangers crashing out of the Scottish Cup, while Kilmarnock were too strong for Inverness Caledonian Thistle and St Mirren beat St Johnstone and Hamilton stunned Dunfermline.

Johnny Russell grabbed a double as Dundee United handed new boss Jackie McNamara the perfect start to the job by dumping nine-man Rangers out of the Scottish Cup.

Russell struck after just 16 seconds, before Jon Daly doubled the advantage and Russell put the gloss on the fifth round victory, which saw Kal Naismith and Ian Black dismissed late on.

Paul Heffernan's double sent Kilmarnock into the quarter-finals as Inverness suffered their second cup exit in eight days.

The substitute fired home in the 58th minute after Inverness were again exposed on the break, although they suffered an unfortunate run of the ball. And the Irishman's clever back-heel with five minutes left ensured Caley Thistle have now lost as many games in those eight days as they had in the rest of the season, with their Scottish Communities League Cup semi-final defeat by Hearts followed by a league defeat at St Mirren.

Esmael Goncalves continued his wonderful start at St Mirren with a brace in their 2-0 win against St Johnstone.

The 21-year-old took his goal tally to four in three games as the Buddies booked their place in the last eight. Goncalves headed home to break the deadlock six minutes after half-time and doubled the hosts' advantage eight minutes later. More to follow
