Bath hooker Ross Batty has been suspended for three weeks after his red card in the 21-19 defeat by Worcester Warriors on Saturday.
The 32-year-old was sent off by referee Ian Tempest in the 63rd minute of the match for a neck-roll tackle at a ruck.
Batty accepted a Rugby Football Union charge of dangerous play and an independent panel ruled he will be free to play again on 5 February.
"A mid-range point was mandated," panel chair Jeremy Summers said.
"Taking in to account all the circumstances, the panel was satisfied that a top-end entry point was not required.
"The player had a clear record, accepted the offence and plainly regretted his actions. As such a 50% reduction from the entry point was allowed."
