Hamilton 0-0 Motherwell
Ziggy Gordon earns an early booking in the Lanarkshire derby as he hauls back Marvin Johnson with the winger racing down the touchline.
An early chance for United in Dingwall as Paul Paton winds up to fire in a shot from distance but he blazes over.
Remember that howitzer he scored against Hearts a few weeks ago? He was in similar territory but lightning didn't strike twice there.
United, though, have started well in the Highland sunshine.
Hearts 0-0 Partick Thistle
Positive start for Hearts and Jamie Walker rounds the goalkeeper but can't produce a finish.

Richard Wilson
BBC Scotland at the Falkirk Stadium
"For Falkirk, the opportunity to overtake Hibs and move second in the Championship. For Alloa, a chance to restore some hope that relegation might be avoided. It is a clash of contrasts at Falkirk Stadium, with the home side confident and capable of crisp, incisive football, while the visitors have to be dogged and gritty in the fight for survival. Given the circumstances, and the strengths of the two teams, it is hard to look past a Falkirk victory."
