Paris - France lock Pascal Pape has lost his appeal against a 10-week ban he received after kneeing Ireland's Jamie Heaslip during their Six Nations clash, the tournament's committee announced on Tuesday.
The 34-year-old, Stade Francais forward's appeal, against the foul in France's 18-11 defeat at Lansdowne Road a fortnight ago, was heard in London.
"The Appeals' Commission have rejected this appeal and as a result the initial 10-week sanction is maintained," the tournament's committee said in a statement.
Heaslip suffered three fractured vertebrae as a result of the foul with the committee saying last week only Pape's "expressions of remorse" had saved him from a longer ban.
Pape, who has 59 caps, is now ruled out for the rest of the Six Nations and can only to return to club and international duty on May 18, the committee added.
The former French captain is set to retire from the international game after this year's World Cup.
France's Six Nations' hopes received a blow on Saturday when they lost 20-13 to Wales in a must-win clash at the Stade de France.
The team won their opening match at home to Scotland before losing in Dublin and again at home to the Welsh last weekend.
