A Motherwell first team player returned a positive Covid test on Tuesday but two repeat checks showed him to be clear.
The unidentified player will isolate for a week. The club issued a statement on Saturday morning.
"We can confirm that a first team player tested positive for Covid-19 earlier this week, as part of our regular testing procedures.
However following two further tests – one through the NHS and another through our private testing facility – he has returned negative results.
The player has not shown any symptoms at any point.
Despite this ‘false positive’, the player will be in self-isolation for seven days as a precaution. He will be tested again prior to his return to training."
