Two rounds remain and nobody has emerged as a clear favorite for the Six Nations title. With the four leaders facing off against each other, this weekend will be critical.
England, France, Ireland and Scotland all have four points from three games.
England will be looking to beat France at the Stade de France for the first time since 2000 tomorrow. England last won the title in 2003; France last took the title in 2004.
"Playing England is always a big match and we will not need to motivate the players," French coach Bernard Laporte said.
Today, Scotland seeks to beat Ireland for the first time in eight years in the last match at the rundown Lansdowne Road stadium before it's refurbished.
Scotland has been the biggest surprise this season, beating France and England.
Ireland named lock Paul O'Connell in the second row after he passed a fitness test on his injured shoulder. O'Connell was injured in the 43-31 loss to France on Feb. 11 and missed the 31-5 Wales win, but is fit to pair up with Malcolm O'Kelly.
Wales hosts Italy in a bottom-of-the-table match today but coach Scott Johnson isn't prepared to let go of his country's title defense easily.
France has recalled scrumhalf Dimitri Yachvili, who'll play in place of Jean-Baptiste Elissalde, as one of two changes from the team which initially struggled to beat Italy two weeks ago.
England recalled Matt Dawson in one of two changes to the team that lost 18-12 to Scotland last month. Only Dawson, wing Ben Cohen and center Mike Tindall were in the last England team to win at the Stade de France, while Lawrence Dallaglio again is a replacement.
In the final round of matches on March 18, it's England versus Ireland, Italy versus Scotland and Wales versus France.
