Playing Rangers' Europa League first leg against Bayer Leverkusen in front of a packed Ibrox may have led to an increase in coronavirus cases according to new figures.
The match was the last played in front of fans in Scotland before the shutdown, with Steven Gerrard 's side beaten 3-1 by their German opponents.
Many other Europa League last 16 ties on March 12 were played behind closed doors, with Sevilla vs Roma and Inter vs Getafe postponed due to the threat of the virus.
However, the UK government did not impose a ban on sporting events until the following week and the SPFL's decision to suspend football across Scotland came the following day.
Now Scottish Government figures obtained by the Scottish Daily Mail suggest that both that match and a Six Nations rugby match were followed by a spike in calls to NHS 111 complaining of COVID-19 symptoms.

Bergamo was the worst affected city in Italy, the initial epicentre of the pandemic.
In February Atalanta took on Valencia in Milan, with 40,000 Bergamaschi travelling to San Siro for the match.
Fabiano di Marco, chief pneumologist at Bergamo's largest hospital, called the exodus on buses, trains and cars "a biological bomb" and blamed the match for the spread of the disease in the city.
