Denmark have named a second-string squad including futsal players for this week's matches against Slovakia and Wales after contract negotiations with first-team regulars ended in deadlock.
The Slovaks say they have asked UEFA to deal with the case and confer "adequate consequences". "That would be the worst-case scenario".
The Danish Football Association (DBU) are locked in a battle with senior Danish players over a feud on commercial rights.
The stand-off is thought to be based around the DBU's desire for more flexible rules about using players in commercial contexts, while the Spillerforeningen wants sponsorship deals to focus on the team instead of individuals.
The DBU on Sunday rejected the players' offer to extend their existing contracts for the next two games which would have postponed further negotiations until after those matches.
Denmark play Slovakia away, while they could also be forced to play with a team of unknowns for their home UEFA Nations League game against Ryan Giggs' Wales on Sunday if things aren't resolved. Articles appear on euronews.com for a limited time. "The board has therefore asked DBU's management that the two worldwide matches will be played with the strongest possible team". "We know that all players understand that we are looking for a collective agreement for Danish football".
Manager Age Hareide and assistant Jon Dahl Tomasson have been temporarily stood down from their positions, with former Arsenal midfielder John Jensen in charge for the next two matches.

There were no immediate indications that the storm had so far affected energy operations in the Gulf of Mexico area. "Little change in strength is forecast during the next few days", the National Hurricane Center said Sunday.
"Where we are now", Jensen said, "I see only losers in the conflict, and Danish football loses most of all".
Eriksen, who released a statement through the Danish Player Association on behalf of the team, said of the situation: "We have to solve this conflict now, not just digging the ditches deeper".
"Let's renew the old deal by one month". Sign it, and we will sit on the plane immediately.
"We are here because we love playing for Denmark, and we are proud of the many millions we earn for the youth and breadth of Danish football, including by taking part in the DBU's events and for their sponsors".
"We feel a lot of support", Eriksen said in comments published by the players' union.
Failure to reach such an agreement left an unfamiliar squad, including players from third-tier club Avarta, fourth-tier Vanlose and four who appeared in the 2016 Futsal World Cup and play for club side Jaegersborg.
