There are five Ladbrokes Premiership matches on Wednesday evening, including the visit of leaders Celtic to Ross County.
The Dingwall clash is live on BT Sport, kick-off 7.45pm, with Brendan Rodgers' side aiming to maintain their unbeaten domestic record against a Staggies team just outside the top six.
Third-placed Hearts, who have conceded fewest goals in the top flight this season, travel to play a Kilmarnock side who are yet to win in the Premiership at Rugby Park in 2016/17.
Rangers have the chance to leapfrog St Johnstone when the sides meet at Ibrox - Mark Warburton's men are unbeaten at home while Saints have won three out of five on their travels.
Motherwell welcome Inverness CT to Fir Park, with the sides separated by a single point in the table. Caley Thistle are aiming for their first away league win of the season when they take on Mark McGhee's men in Lanarkshire.
There's a big game at Dens Park as bottom club Dundee play host to a Partick Thistle team who are just a point above them - both teams have managed only one league victory so far.
