One player out of 1,043 people tested has returned a positive result in the Premiership's latest round of coronavirus testing.
It was the highest number of tests carried out in one day since testing began on July 6, and the lowest number of positive results.
The Premiership returned last week after being suspended for more than four months due to the coronavirus pandemic.
The action continues this weekend with third-placed Sale facing leaders Exeter Chiefs at the AJ Bell Stadium.
The Sharks' three-game winning streak was ended by Harlequins last weekend while Exeter's win over Leicester extended their lead at the summit to eight points.
