Three further Kilmarnock players have tested positive for Covid-19, taking the number of cases at the Scottish Premiership club to six.

All six are self-isolating and Friday's Scottish Premiership visit of Motherwell is now in doubt.

The SPFL are awaiting information from the Ayrshire and Arran Health Board's Test and Protect team before they "determine the implications".

Earlier on Thursday, manager Alex Dyer said his squad were "in limbo".

After three players had their positive tests from earlier in the week confirmed by the NHS, Kilmarnock were unable to train until the results of a fresh batch of tests on Thursday were known.

Dyer said one of the initial three players felt unwell on Sunday after the victory at St Mirren the previous day and was not allowed to train. The other two have been asymptomatic.

"We thought it was just a bug because of the changing of the weather then we found out three players tested positive," he explained.

''We won't feel sorry for ourselves - it's part of life. We'll train when we are allowed to and do all the things we can. If they let us play the game we'll do the best we can."

The trio who returned positive tests on Thursday will now also have NHS tests.

"The health and wellbeing of our players and staff remains paramount and we wish all those affected a speedy recovery," Kilmarnock said.

Uefa guidance, which Scottish football's Joint Response Group is adhering to, is that any side with 13 available players - including one goalkeeper - should fulfil their fixture.
