"The World Footballers' Association will not sit idly by as the rights of our players are being abused," FIFPro said.
The FIFPro delegation, led by board member Mads Oland, will also include members of the International Trade Union Confederation concerned about the plight of migrant workers in Qatar.
Focusing on projects linked to the 2022 World Cup, rights group Amnesty International recently published a report cataloging how some construction workers in the Gulf nation are exposed to dangerous working conditions, poor living standards and the non-payment of wages.
"While FIFPro's primary concern must be the players, we will not overlook the tragedy which is currently unfolding in Qatar," FIFPro said in a statement. "FIFPro is seriously concerned by allegations of human rights violations in the construction of World Cup stadia and related infrastructure."
