Harlequins prop Kyle Sinckler has been charged under Law 10.4.G (dangerous charging) following the fixture against Northampton last Friday.
Sinckler was subsequently cited after a tackle on Northampton back-row Samu Manoa in the 55th minute of the Premiership match at Franklin's Gardens.
His case was dealt with by Jeremy Summers as a Sole Judicial Officer at the London Bloomsbury Holiday Inn.
Sinckler pleaded guilty and is banned for one week. He is free to play again on the March 9.
