Ma'a Nonu has been ruled out of Toulon's Top 14 final against Racing 92 in Barcelona this weekend.

Nonu was knocked out suffering concussion in his side's win over Montpellier.

Dan Carter will play for Racing with a crowd in excess of 95 thousand expected at the home of Barcelona football club.

The match is being staged in Spain due to the Stade de France being unavailable because of Euro 2016.
