London Irish back Delon Armitage has been banned for five weeks for a dangerous tackle on Bath's Tom Biggs.
The Rugby Football Union said it hoped the England player would learn lessons from his fourth suspension of 2011.
Armitage, 27, was also found guilty of striking lock Dave Attwood with a knee during the same match.
Judge Jeff Blackett, the RFU's disciplinary chief, said: "We accept that both these incidents were reckless and not malicious."
