Saracens back-row Jacques Burger has been given a one-week ban for striking an opponent in their European Champions Cup quarter-final tie at Racing Metro.
The 31-year-old was cited on Wednesday for striking Racing scrum-half Maxime Machenaud in the second half of Sarries' 12-11 victory.
The Namibia international pleaded guilty to the charge at a disciplinary hearing on Thursday.
Burger will miss Saracens' Premiership game at home to Leicester on Saturday.
The independent judicial officer at the European Professional Club Rugby hearing, Welshman Simon Thomas, upheld the citing complaint.
He found the offence was reckless and warranted a red card, but that it was at the low end (a two-week ban) of World Rugby's sanctions.
However, Thomas reduced Burger's ban by one week because of his guilty plea, an early expression of remorse, in addition to his good conduct during the hearing and a clean disciplinary record.
Burger will be available to play for Saracens in their European Champions Cup semi-final tie with Clermont Auvergne on 18 April.
