Poland will open their Nations League campaign against Bosnia and Herzegovina in Warsaw on September 25, followed by a September 28 match against Sweden in Stockholm.
The team will face Romania in Warsaw on October 2 before travelling to Zenica to play Bosnia and Herzegovina again on October 5.
The training camp in Warsaw begins on Monday, with players due to arrive by 6 p.m. The first training session is scheduled for Tuesday.
'Living legend'
Lewandowski, who until recently played for Barcelona, received a call-up as expected. Urban said the 38-year-old striker's playing time would depend on his condition.
"We will react depending on how Robert feels," Urban said. "If we think he can rest, we will do that. If we need him until the end, he will play. It will look different from match to match."
He later elaborated, saying: "Robert has reached such a status in Polish football that he is a living legend. If he says after one of the matches that he is ending his career because he does not want to play at 50 percent or 70 percent, he has the right to do that. He has earned it through his performances for the national team."
He added: "We have to slowly prepare for a national team without him. If he makes it to Euro 2028, he will be 40 and will finish then, like 40-year-old Bosnian Edin Džeko now. Robert is in excellent health, but we have to be prepared. There are new names among the strikers."
Tymoteusz Puchacz, Adrian Benedyczak, Wojciech Mońka and Wiktor Nowak are the new names in Urban's squad.
Puchacz, a 27-year-old wide midfielder, last played for Poland in November 2024. He received positive reviews while playing for Sabah Baku this summer, and his assists helped the Azerbaijani champions reach the main stage of the Champions League.
Benedyczak, a 25-year-old striker, has scored four goals in the Turkish top flight this season for Kasimpasa.
Mońka, 19, has been a regular starting centre-back for Polish champions Lech Poznań in recent months. Nowak, a versatile 21-year-old who joined Slavia Prague, has emerged as one of the Czech league’s revelations and is joint top of the scoring charts with five goals.
Mońka and Nowak have so far played for Poland's under-21 team, coached by Jerzy Brzęczek.
Urban has selected five players who are still eligible for the under-21 side.
Kacper Urbański is also returning to the senior squad after an 18-month absence. He has become an important player for Górnik Zabrze, who have made a strong start to the season in the Polish top flight.
Other players from Polish clubs include goalkeeper Mateusz Kochalski, who recently returned from Azerbaijan and joined Wieczysta Kraków; Norbert Wojtuszek of Jagiellonia Białystok; and the experienced Widzew Łódź duo of defender Przemysław Wiśniewski and striker Karol Świderski.
Urban also selected Mainz defender Kacper Potulski and Mateusz Żukowski, a striker who plays for second-tier German club FC Magdeburg.
Poland's final two Nations League matches are scheduled for November, away to Romania on November 14 and at home against Sweden in Wrocław three days later.
Poland were relegated from Division A under former coach Michał Probierz in the autumn of 2024 after finishing last in a group containing Portugal, Croatia and Scotland.
Scotland also went down after losing in the relegation playoffs.
Poland are now seeking a return to the top division. The winner of their Division B group will earn direct promotion, while the runner-up will have a chance to advance through a playoff.
The third-place team will enter a playoff to avoid relegation, while the fourth-place team will drop to Division C.
Path to Euro 2028
Urban said Poland would take the Nations League seriously, noting that the competition could provide an alternative route to the European championships if the team fails to qualify through the traditional route.
"It is also a path to the European championships if we don't qualify in the traditional way,” Urban said.
For some teams, the Nations League, which replaced most friendly matches, provides an opportunity to test younger players. For others, it is a chance to improve their position in the European hierarchy.
Poland will compete outside the top division for the first time, in Division B.
"We are not in a situation where we have just come back from the World Cup and can now look for new solutions, treating the Nations League as a testing ground. That did not happen; we were not at the World Cup. We have to take the Nations League seriously," Urban said.
He told reporters that he would give opportunities to new players and try different approaches, but winning would remain the priority.
"There will be no situation where we experiment at the expense of the result. We will try to field our strongest lineup for every match," he said.
