Ulster centre Stuart McCloskey has been banned for four weeks as a result of his red card offence in last Friday's Pro12 match away to Edinburgh.
The 22-year-old was sent off for what was deemed a dangerous tackle on opponent Hamish Watson during the second half at Murrayfield and he was found guilty of foul play.
McCloskey will miss this Friday's sellout Pro12 game against the Scarlets in Belfast, plus Ulster's two matches in March away to Newport Gwent Dragons and at home to Cardiff Blues.
Despite being found guilty, the disciplinary panel felt it was at the lower end of the scale.
An official Pro12 statement said: "The committee added one week to reflect the need for a deterrent for this type of offence, but reduced it by one week having noted the player's previous unblemished record, among other mitigating factors."
