Will Skelton has been banned for four weeks for a dangerous late tackle on Brice Dulin in beleaguered Saracens' crucial European Champions Cup win over Racing 92 on Sunday.
Skelton was shown a red card just before half-time at Allianz Park after his shoulder struck full-back Dulin's head.
Sarries went on to win 27-24, setting up a quarter-final at Leinster, a day after their relegation to the Championship at the end of the season was confirmed due to salary-cap breaches.
Skelton attended an independent disciplinary hearing in London on Tuesday and the Australian is set to miss the European champions' Premiership clash with Harlequins, two encounters with Sale Sharks – in the league and Premiership Rugby Cup – and a top-flight game at Wasps.
The towering 27-year-old's guilty plea, good disciplinary record and expression of remorse were taken into account when his sanction was handed out.
Skelton will be available to return against Northampton Saints at Franklin's Gardens on February 29.
Sarries travel to Dublin to face Leinster at the Aviva Stadium in a repeat of last year's final in the first week of April.
