Tonga prop Sona Taumalolo has been ruled out of Friday night's clash with Wales after receiving a four-week ban.
Taumalolo's punishment comes following his sending-off for fighting with lock Yoann Maestri, who was also dismissed, during last weekend's 38-18 win over France in Le Havre.
While Maestri escaped further action when the duo appeared before a disciplinary committee in London, Taumalolo's offences were deemed to be more serious.
A statement read: "Both players had accepted prior to the hearing that their actions had warranted a red card, and the committee deemed that Sona Taumalolo's offence was in the mid-range of the IRB's sanctions (five weeks), allowing one week off for mitigating factors."
Taumalolo will be free to resume playing on December 16. Both players have the right of appeal.
