The former All Blacks wing flipped his car while driving after Toulon beat Perpignan in a French Top 14 match last Sunday (NZT).
Savea's wife Fatima brought the accident to the world's attention by tweeting details of it and her relief he had not been injured. She also emphasised that Savea was simply tired and hadn't had any alcohol, saying he had been sober for eight months.
Toulon tweeted on Tuesday to back up those claims, confirming that Savea's blood alcohol test following the accident was negative.
"Following the numerous comments on the accident @juliansavea7, Rugby Club Toulonnais wishes to clarify that the blood alcohol test was negative. The club has never doubted the integrity of its player and is happy to know he is unscathed," Toulon tweeted.
Savea, a prolific points scorer for the All Blacks, had finally broken his try-drought in their 26-16 weekend win.
The Saveas are now in Dubai for a holiday with Toulon having a two-week break from competition while international rugby takes the spotlight in Europe.
