Two of Poland's squad have tested positive for Covid-19 ahead of their trip to play England in a World Cup qualifier at Wembley on Wednesday, a Polish FA spokesman said on Tuesday.
"The Polish national team has undergone further tests for the presence of coronavirus. Unfortunately, the results of Grzegorz Krychowiak and Kamil Piatkowski are positive," team manager Jakub Kwiatkowski said on Twitter.
"Due to the fact that Krychowiak is a [recovering] player, the Polish Football Association started talks with Uefa in order to clarify the matter and allow the player to play with England."
Kwiatkowski said he had also tested positive for the virus.
Poland's Leeds midfielder Mateusz Klich and backup goalkeeper Lukasz Skorupski tested positive last week.
It is another setback for the Poland squad, which has not yet travelled to London, after record goalscorer Robert Lewandowski was ruled out of the clash because of a knee injury.
Poland have four points from their first two games, two behind Group I leaders England.
