Racing 92's Australia international Kurtley Beale will miss the European Champions Cup quarter-final against Clermont after receiving a three-week ban on Wednesday for a Top 14 red card.
Beale, 31, was sent off for a dangerous tackle on France centre Arthur Vincent in Racing 92's victory over Montpellier on his home debut Friday.
If Racing beat Clermont on Saturday, he will be sidelined for a semi-final the following weekend against Leinster or defending champions Saracens.
The French league's disciplinary commission opted against the maximum six-week sanction due to the "absence of aggravating factors" and Beale's acceptance of the blame and remorse.
Racing can appeal the decision within seven days.
