Leicester Tigers' Brown banned for two weeks after swearing
Brown, 38, was sent off in the 71st minute after making head contact in a tackle and swore at as he left Welford Road Stadium, with the Tigers losing the Premiership Rugby match 21-19.
The former England player was handed a five-week ban by an independent disciplinary panel, with three weeks suspended until the end of next season.
Brown was also ordered to give "a presentation on the values of the game which is to be recorded and shared for educational use and to help demonstrate why such behaviour will not be tolerated in rugby".
"Such offending is a direct undermining of the authority of the match officials and an attack on the game's ethos and core values," the panel stated.
