Leicester hooker and England squad member George Chuter has been banned for eight weeks for stamping on Wasps counterpart Raphael Ibanez.
The offence took place on March 4 in the Powergen Cup tie which Wasps won 22-17, and the Rugby Football Union announced Chuter's punishment on Tuesday night.
Chuter admitted his guilt at a London hearing and will next be available to play on May 2.
Presiding at his disciplinary hearing was an RFU panel made up of Judge Jeff Blackett, who chaired the meeting, Peter Budge and Jeff Probyn.
They had the power to ban Chuter for any length of time between four weeks and 12 months.
Chuter had already been suspended by Leicester following the incident when the 29-year-old's offence cost him his chance of appearing in England's remaining RBS 6 Nations Championship matches.
He was on the bench for Andy Robinson's side in their Calcutta Cup match against Scotland at Murrayfield on February 25.
Speaking after the incident involving Ibanez, Chuter was remorseful.
''I very much regret this whole incident and I would like to personally apologise to Raphael Ibanez for my actions,'' he said.
''I had no intention of causing any harm to him and I just wish I could wind the clock back to put things right.
''I have never been a dirty player and am devastated that I have let down the club and its supporters and that I may have missed the opportunity to make my England debut during the Six Nations.''
