Clermont lock Jamie Cudmore has been banned for 10 weeks for stamping during Saturday's Heineken Cup victory over Saracens.
The fiery Canadian international faced an independent disciplinary hearing in Dublin after being cited for the incident involving Jacques Burger.
Cudmore pleaded not guilty to kicking and/or stamping on Saracens flanker Burger, who was left with a mouth wound which required stitches.
The hearing decided the offence was top entry, which entails a suspension of nine weeks.
However, Cudmore's previous disciplinary record saw the ban increased by a week and he will be unable to play again until December 20, missing three rounds of the Heineken Cup.
Munster centre Sam Tuitupou was handed a three-week ban after he was found guilty of a dangerous tackle on London Irish's Paul Hodgson during Saturday's Heineken Cup meeting between the two sides at the Madejski Stadium.
The former New Zealand three-quarter was cited for allegedly lifting scrum-half Hodgson and driving him into the ground.
Tuitupou was handed a yellow card for the incident during his side's 23-17 defeat and the ERC disciplinary panel decided that the tackle was at the lower end of the scale for such an offence, resulting in the three-week suspension.
The independent judicial officer, Simon Thomas of Wales, initially increased the recommended suspension by a week to take into account the need to deter tackles of such a nature, but balanced that by decreasing the ban by a week due to Tuitupou's conduct at the hearing.
The suspension puts a real strain on the Irish province's midfield resources with Lifeimi Mafi also on the sidelines after being handed a seven-week ban for a dangerous tackle in a Magners League match last week. Tuitupou will be free to play again on November 1.
