Australia lock Rob Simmons has been given an eight-week ban after being cited for a dangerous tackle during last Saturday's Test against France.
Simmons was suspended by the Six Nations, which oversees disciplinary issues during the November Tests, after being cited for a tip tackle on France openside flanker Yannick Nyanga.
He will miss Saturday's Test against England at Twickenham, as well as the games against Italy and Wales on the final two weekends of the tour. He is free to return to action on February 25.
A statement released on Wednesday by the Six Nations says a ban of fourteen weeks was reduced to eight because of mitigation, including Simmons' exemplary previous disciplinary record.
