Ulster lock Kieran Treadwell has been handed a three-week ban following his yellow-card incident in the seventh round clash in the Pro14 against Scarlets.
Treadwell was sin-binned in the 17th minute for a dangerous tackle on Scarlets' Javan Sebastian after consulting with TMO Brian MacNeice.
As a result, he appeared before Judicial Officier Robert Milligan QC and was proved guilty of breaching Law 9.13 that deals with "a player must not tackle an opponent early, late or dangerously. Dangerous tackling includes, but is not limited to, tackling or attempting to tackle an opponent above the line of the shoulders even if the tackle starts below the line of the shoulders."
The 25-year-old was initially handed a six-week ban that was reduced by half taking into account his guilty plea, conduct during hearing and other mitigating factors.
He will now miss the Pro14 game against Edinburgh and the opening two rounds of the Heineken Champions Cup against Toulouse and Gloucester and free to play again from midnight on December 19.
