Five players and two staff from six different clubs have tested positive in the latest round of Premiership Rugby coronavirus testing.
The results are from the second set of tests to be conducted this week, which saw 956 players and club staff tested on Wednesday as part of their COVID-19 screening programme before the return of Premiership Rugby on Friday night.
Harlequins play Sale at the Twickenham Stoop in a highly-anticipated game that will see England international Manu Tuilagi make his Sharks debut after he joined from Leicester last month.
The match - which will be played behind closed doors - marks the return of top-flight rugby in the northern hemisphere for the first time in five months.
