The game at the Olympic Stadium in the Finnish capital kicks off at 8:45 p.m. Warsaw time.
The Poles, captained by Inter Milan midfielder Piotr Zieliński, are aiming for a third straight win to strengthen their lead in the qualifying group.
Poland are ranked 34th worldwide by football's governing body FIFA, while Finland are No. 69 in the FIFA table.
The match will be closely watched following star striker Robert Lewandowski's announcement that he will no longer play for the national team as long as head coach Michał Probierz remains in charge.
Lewandowski's announcement came after a statement by the Polish Football Association (PZPN) that Zieliński had been appointed the new team captain, following a decision by Probierz.
On Monday, Probierz told a news conference that his decision to strip Lewandowski of the captain's armband was made "solely for the good of the team."
In an interview published on Monday, Lewandowski said he had lost trust in Probierz.
"The coach broke my trust," the 36-year-old said. "I want to stress that this isn’t about me being offended or putting myself above the team. For years, I’ve always given everything I had. The national team has always been my top priority. But what happened has hurt me deeply."
On Friday, the Polish team defeated Moldova 2–0 in a home friendly at the Silesian Stadium in the southern city of Chorzów. Lewandowski attended that match but did not play.
The Polish team opened its World Cup qualifying campaign in March with home wins over Lithuania (1-0) and Malta (2-0).
Poland’s qualifying Group G also includes the Netherlands and Finland.
The 2026 World Cup will be held from June 11 to July 19, 2026 in the United States, Canada and Mexico.
Poland reached the last 16 of the 2022 World Cup in Qatar before being eliminated by eventual runners-up France.
