Sale have made a complaint to the Rugby Football Union after information was allegedly leaked to opponents Bristol earlier this month.
Bristol fought back from 15-0 down to win the Aviva Premiership encounter 24-23 at the AJ Bell Stadium on New Year's Day and an RFU investigation is underway.
Sale director of rugby Steve Diamond has since confirmed Tom Arscott is the player being probed - his brother Luke plays for Bristol - and has been suspended until further notice.
The spokesman said: "The RFU are investigating a complaint made by Sale Sharks in relation to the passing of information to the opposition team ahead of the match against Bristol earlier this month."
Bristol Rugby responded by issuing a statement: "Bristol Rugby has been made aware of a complaint from Sale Sharks, which is now being investigated by the RFU.
"The club are absolutely confident of no wrongdoing in this matter and will fully co-operate with the investigation. We will make no further comment at this time."
Sale are next in action when they host the Scarlets in their final European Champions Cup group game on Saturday.
Bristol - who are bottom of the Premiership, seven points adrift of 10th-placed Sale - welcome Cardiff Blues in the European Challenge Cup this weekend.
