The Scots are rooted to the bottom of Group A1 after three successive defeats to Poland, Portugal and Croatia.
Steve Clarke’s side haven’t recorded a competitive victory in over a year, dating back to their 3-0 win over Cyprus in September 2023, and things could go from bad to worse for the hosts when high-flying Portugal arrive in Glasgow.
Roberto Martinez’s men have won all three of their games so far this campaign, beating Croatia and Scotland 2-1 before a 3-1 win in Poland on Saturday.
Portugal are without centre-back Goncalo Inacio due to injury, with Renato Veiga making his international debut against Poland.
Cristiano Ronaldo will feature at some point in what could be his final match in Britain.
Scotland have no new injury concerns following their 2-1 defeat in Croatia, with uncapped Rangers midfielder Connor Barron being drafted in to replace James Forrest.
Clarke is already without a host of regulars with Angus Gunn, Lawrence Shankland and Greg Taylor all pulling out due to injury and joining John McGinn, Kieran Tierney, Aaron Hickey, Scott McKenna and Lewis Ferguson on the treatment table.
