The Steelmen, meanwhile, ended a run of four successive losses with a 0-0 draw at home to Aberdeen in midweek.
Dundee United moved up to fifth in the Scottish Premiership with a comfortable 2-0 win over Kilmarnock on Wednesday evening.
Manager Micky Mellon would have been pleased to see both Marc McNulty and Lawrence Shankland on the scoresheet as the Tangerines have been heavily reliant on forward Nicky Clark, who has seven of their 16 league goals this campaign.
Wednesday's triumph was just their fourth win in 15 matches, although United have won three of their last four home games and have only lost two of their last nine fixtures in the top flight.
Dundee United are winless in their last 10 Scottish Premiership matches on Boxing Day. Their last such win however was at home to Motherwell back in 1996.
Securing the three points on Saturday could see Mellon's men consolidate fifth spot, moving five points clear of the Steelmen, who sit one place below them.
Motherwell's poor run of form in the league continued as an uneventful encounter at Fir Park ended goalless on Wednesday evening.
Steve Robinson's side have failed to win any of their last seven matches in all competitions, five of which have been at home.
The Steelmen however travel to Tannadice on Saturday with a better record on the road, winning four of their nine Scottish Premiership away fixtures.
This will be Motherwell's first top-flight away game at Dundee United since a 3-0 win in February 2016 under former boss Mark McGhee.
The Steelmen have won their last two away league matches against newly-promoted sides, winning against St Mirren in February 2019 and Ross County in December 2019. They last won three consecutive away games against promoted sides in the top flight back in February 2001.
Motherwell, who have won three of their last four Scottish Premiership matches on Boxing Day, could move back into fifth spot above the Tangerines with a victory on Saturday.
