The Poles, who are reigning world champions, will take on Serbia in their next match in Kraków, southern Poland, on Saturday.
Poland is jointly hosting the 2021 EuroVolley championships, which are also being held in the Czech Republic, Estonia and Finland from September 1 to 19.
The Polish team, under Belgian coach Vital Heynen, reached the quarterfinals of the volleyball tournament at this summer's Tokyo Olympics, where it was knocked out by eventual gold medal winners France.
