Bath scrum-half Michael Claassens has signed a "pre-agreement" with Toulon, according to reports in France.
The South African scrum-half is out of contract at the end of the season but is yet to sign an extension with the West Country side which he joined back in 2007 from the Cheetahs.
Claassens' move however is dependent on the future of former England fly-half Jonny Wilkinson according to La Provence.
Wilkinson is yet to make a decision on whether he will retire at the end of the season, setting a February deadline on his announcement.
If Wilkinson does retire, then Claassens will link up with the French side with Frederic Michalak starting at fly-half instead of his current position at scrum-half alongside Wilkinson.
However if Wilkinson does decide to remain with Toulon for another season, then Claassens' move will be in jeopardy, raising the possibility of him staying at The Rec.
