Gloucester fly-half Danny Cipriani has ended a dismal week with a red card against Munster, two days after being left out of England's squad for the autumn internationals.
The 30-year-old was shown a red card after his shoulder made contact with Rory Scannell's head in a 29th-minute tackle in the Champions Cup tie.
Cipriani apologised to Scannell on his way off the field.
His side were 5-3 down at the time, and went on to lose 36-22.
Cipriani was left out of England's 36-man squad on Thursday, with coach Eddie Jones emphasising that he is third-choice fly-half behind Owen Farrell and George Ford.
Toulouse flanker Jerome Kaino received a five-week ban after being shown red for his shoulder to the head of Bath centre Jamie Roberts last weekend.
