Gloucester's Albert Tuisue has been banned for two weeks after receiving three yellow cards this season.
The 29-year-old back row got his third yellow card for a dangerous tackle against London Irish on 31 December.
He had previously been sin-binned twice in October, once for dangerous play in a ruck against Exeter, and once for charging against Bath.
He will miss Friday's Premiership game against Saracens and the European Champions Cup tie against Leinster.
