Linfield could receive a bye in the Champions League after their preliminary round tie with Kosovo side FC Drita was postponed to a Covid-19 issue.
The preliminary round tie had been due to kick-off at 6pm on Tuesday in Nyon, Switzerland, but a decision taken by the Swiss health authorities saw the match cancelled hours before it was due to start.
A FC Drita player tested positive for Covid-19 on Friday and - in accordance with UEFA's Return to Play protocol - was put into quarantine along with one team-mate after tracing found he had come into close contact with the affected player.
A second member of the side produced a positive coronavirus test on Monday and it forced the fixture to be called off after the whole squad was put into quarantine.
UEFA's new regulations, introduced to deal with complications arising from the coronavirus, indicate that the game must be played by Friday, provided the affected team have the requisite minimum number of players (13 including a goalkeeper).
Otherwise, the affected team will forfeit the game.
UEFA's Control and Disciplinary Body will examine the matter tomorrow. The winners will face Legia Warsaw in the next round.
"This second positive test of a player who was in contact with other members of the delegation over the last days has prompted the Swiss authorities to put the whole Kosovan team into quarantine," a statement from UEFA read.
"Accordingly, the upcoming fixture cannot be played. The matter will now be submitted to the UEFA Control and Disciplinary Body, for a decision to be taken in accordance with Annex I of the 2020/21 UEFA Champions League regulations, which was approved by the UEFA Executive Committee last week.
"UEFA would like to reinforce the importance for all teams, players, officials and all those involved to fully respect the UEFA Return to Play Protocol."
