The former England player, who announced earlier this week that he will retire from the sport this summer, played his part in the 26-3 victory at the Millennium Stadium in Cardiff.
"I can't say enough just how proud I am to be part of this team, to have been able to play in this competition, against teams like that," the 34-year-old is quoted as saying by the Daily Mail. "We've had a hell of a time, there's a week left in our season so we'll carry on."
When asked where this victory ranks among his career highlights, Wilkinson added: "It's up there - a lot of relief, a lot of excitement, sheer adulation, at the moment I'm just trying to take it all in.'
Toulon return to action next weekend when they take on Castres.
