The Staggies came out on the winning side of a five-goal thriller with Livingston on the weekend, whilst the Buddies were victorious over St Johnstone last time out.
Match preview
Following a wretched 10-game winless run in the Scottish Premiership which stretched all the way back to the beginning of December, Ross County finally returned to winning ways by beating basement dwellers Livingston on Saturday afternoon, although the Staggies made hard work of the contest.
A sensational first-half brace from Eamonn Brophy had Derek Adams's men two goals to the good after just 27 minutes, but the visitors at Global Energy Stadium levelled the scores with Bruce Anderson netting a double of his own, before substitute Josh Sims popped up with a 92nd-minute winner to send the home crowd into raptures.
After a much-needed maximum last time out, Adams's men have moved onto 22 points from 26 Scottish Premiership standings, with Tuesday night presenting the opportunity for Ross County to leapfrog 10th-placed St Johnstone with maximum points, and the chance to close the 10-point gap to sixth.
With 14 of their 22 top-flight points arriving at the Global Energy Stadium this season, the Staggies will be happy to be playing in front of their home faithful once again on Tuesday night, having endured three-straight away defeats prior to Saturday's conquering of Livingston.
Looking to fire Ross County towards safety at the business end of the campaign, Simon Murray is currently leading his side's Golden Boot race with seven goals from 26 Premiership matches, meaning that the 31-year-old has already surpassed his highest-scoring term in the top flight.
After becoming only the third Premiership outfit to be defeated by bottom side Livingston this season, St Mirren responded in confident fashion at the SMISA Stadium on Saturday afternoon, beating St Johnstone in order to maintain the Buddies' healthy buffer over the bottom half of the table.
An unfortunate own goal from Saints goalkeeper Dimitar Mitov handed the hosts the lead going into the half-time break, with Mikael Mandron's sixth goal of the league campaign doubling St Mirren's advantage after an hour, ultimately putting the contest beyond the visitors.
Steve Robinson's men are on course to improve last season's final standing of sixth, with the Buddies currently fifth in the top-flight table, six points ahead of Dundee in sixth and eight better off when compared to seventh-placed Hibernian, who captured some notable talent from Sunderland and Bournemouth during the January transfer window.
St Mirren have fared poorly at the Global Energy Stadium in recent times, losing their last three matches at the home of Ross County, with a late Jordan White strike back in November handing the Staggies a narrow home success over Robinson's side.
