Lotus Renault GP announced on Wednesday evening that Bruno Senna will race alongside Vitaly Petrov at this weekend's Belgian Grand Prix at Spa-Francorchamps.
Renault is set to release more details about the loss of Nick Heidfeld's race seat on Thursday.
In a brief statement, following intense speculation, the team announced that Bruno Senna will be driving alongside Vitaly Petrov this weekend at Spa-Francorchamps.
"A press release with further details on the matter will be issued tomorrow morning," it said.
Additionally, 27-year-old former reserve driver Senna will speak to reporters in the FIA press conference.
German Heidfeld's management has not been available to comment, but the Daily Telegraph said he desperately tried to retain the seat "before a judge on Wednesday".
Grosjean says 'we'll see' to Renault rumours
Romain Grosjean says speculation his formula one career is set to speed up with Renault is "quite funny".
Although Bruno Senna has been named as dumped Nick Heidfeld's replacement at Spa-Francorchamps, rumours insist the Eric Boullier-managed Frenchman Grosjean is a contender for the seat once his GP2 title is wrapped up.
The 25-year-old, whose F1 career got off to an abortive start amid the 'crashgate' scandal in 2009, seemed to acknowledge at least that a ride during a Friday morning practice session is possible.
"It's quite funny to hear rumours; speculation will always be there in formula one," said Grosjean.
"At the moment, it's not something we're thinking about. First of all, there is business to finish in GP2 then, if the opportunity presents itself later in the season, we will see."
