Mitchell to go under the knife

Toulon's Australian back Drew Mitchell is to undergo an operation on a groin injury tomorrow, Toulon announced, adding that they hoped the 70-times capped Wallaby would return to fitness for the start of next season.

Mitchell, 32, also announced the operation through Twitter, saying he would be back in three months, having not played since Toulon's defeat by Clermont on April 3.

Toulon, however, will welcome back Wales full-back Leigh Halfpenny for the Top 14 play-offs.
