Racing's fly half Jonathan Sexton

Ireland fly-half Jonathan Sexton will play his first game in 12 weeks after national coach Joe Schmidt took a gamble to start him in the defending champion's Six Nations clash with France on Saturday at Lansdowne Road.
The 29-year-old -- who has not played since the victory over Australia on November 22 after suffering a third concussion in a calendar year -- replaces Ian Keatley, who played in the opening 26-3 victory over Italy last Saturday.
Fellow veterans No8 Jamie Heaslip and flanker Sean O'Brien also return to the starting XV, the former after recovering from shoulder and knee injuries and the latter will play his first Test since the heroic loss to world champions New Zealand in November 2013.
O'Brien, who has played just 50 minutes of rugby since September last, would have played in the Italy game but for feeling a pain in his hamstring in the match warm-up.
The player who replaced him in the starting line-up for the Italy game Tommy O'Donnell like Keatley did little wrong in the match -- indeed the former scored a try -- but both drop out of the matchday 23.
Rory Best -- Ireland's most capped hooker -- is able to start after being taken off early in the second-half of the Italy game with concussion.
There is a recall to the bench for the experienced prop Cian Healy, who hasn't played test rugby since Ireland clinched the Six Nations title, on icon Brian O'Driscoll's final international, with victory over the French in Paris last March.
Ireland are bidding to win their ninth successive match against a France team who also started the Six Nations with victory, at home to Scotland, but who have won just three times away from home since coach Philippe Saint-Andre took over after the 2011 World Cup final.
However, the last three games between the two sides have been tight affairs, two draws before Ireland -- who will be captained by legendary lock Paul O'Connell winning his 98th cap -- prevailed 22-20 in Paris.
