Vitaly Petrov will be back up and running next weekend in Canada, according to Renault team ambassador Jean Alesi.
Russian Petrov crashed near the end of the Monaco Grand Prix and, according to Italy's La Gazzetta dello Sport, he was discharged after just one hour following some hospital checks.
"Petrov is fine," former F1 driver Alesi is quoted as saying by AS sports newspaper, "he only got a hit in the ankle.
"It's always a worry when a driver is unable to get out of a wreck, but thank god the car did its job," he added.
Petrov, 26, also confirmed he will be fit for Montreal next weekend, despite fearing immediately after the crash that he had broken his leg.
"At the hospital, they did a full body check and analysis and it looks like I'm fine. I need just a little bit of rest and then we'll see what is going on," he added.
Frenchman Alesi agreed with Petrov that the crash was Adrian Sutil's fault, and said he has been impressed with the Russian's 2011 form.
"His first podium in Australia gave him great confidence and he has maintained that level ever since," he said.
