"Mouthy" Joe Marler was accused of "cheap trash talk" for his insulting comments towards an opponent's mother.
Harlequins prop Marler was hit with a six-week ban - four of which have been suspended - for comments made towards Bristol forward Jake Heenan at the Twickenham Stoop.
Marler's comments made during a first-half scrum in the Quins' defeat caused a mini brawl to erupt between players, with Bears flanker Heenan clearly incensed by Marler's behaviour.
