Auto Motor und Sport reports that Romain Grosjean could lose his F1 race ride with Renault for the next round in Brazil to the team's reserve driver, Lucas di Grassi, who like Grosjean is a veteran of the GP2 series. AMS claims the  banning of Grosjean's manager Flavio Briatore has helped pave the way for his dismissal, although the Frenchman has also struggled since replacing Nelson Piquet Jr. at midseason.
