The Danish soccer association, known as the DBU, has named players from lower divisions for upcoming matches against Slovakia and Wales after members of the first-string squad walked out in the wake of pay disputes.
The original squad ranks ninth in the world and reached the last 16 at this year's World Cup.
However, the latest published list shows that the new team include players from the national futsal team, a five-a-side soccer game played mainly indoors on small hard courts.
Negotiations have reached a deadlock between the players' union and the DBU mainly over the rights of players, including Denmark's top midfielder Christian Eriksen who plays for Tottenham Hotspur in the Premier League, to make individual sponsorship agreements with companies competing with national team sponsors.

Denmark is scheduled to play Slovakia in a friendly match on Wednesday and Wales in a Nations League group stage match on Sunday.
Coach Aage Hareide will not be in charge of the team as the DBU does not want him to manage a side he did not pick himself.
The players union has made a second offer on Tuesday to extend their existing contracts which would have postponed further negotiations until after the two games.
The DBU has not yet responded, but rejected the same offer on Sunday.
The DBU last year had to cancel a World Cup qualifying match for the women's national team against Sweden, also due to a contract dispute.
