Dundee United canceled training ahead of Saturday’s game against Rangers after a player tested positive at Covid.
The club is awaiting further PCR test results, however, the confrontation at Ibrox is still expected to continue.
State teams under the SPFL rules must have 13 fit players, including a goalkeeper, for a match to take place and, in addition, 10 of the players must be over 18 years of age.
It is understood that the team spent a Christmas night in Newcastle over the weekend following the defeat to Livingston.
Dundee United are fourth in the Premiership after an impressive start to the season under Thomas Courts.
Covid restrictions in Scotland tightened
People in Scotland should limit socialization to just three families amid rising cases of the Omicron variant, Prime Minister Nicola Sturgeon said.
Introducing the guidelines ahead of the holiday season, Ms Sturgeon said, “We are not asking you to cancel or change your plans and we are not proposing limits on the size of family reunions.”
He added: “My key request today is this: before and immediately after Christmas, please minimize your social intermingling with other families as much as possible.
“However, if you plan to socialize, at home or in public places indoors, we ask that you limit the number of families represented in your group to a maximum of three. And make sure you take a test before you go.”
