Bruno Senna will drive for Lotus Renault Grand Prix in the Belgian GP at Spa this weekend, the team has announced.
Senna drove in Friday free practice at Hungaroring, where rumours were rife that the team was looking to replace the 34-year-old German with Senna for the rest of the season.
Heidfeld was an 11th hour replacement for the injured Robert Kubica, taking the seat alongside Vitaly Petrov just before the start of the season. He currently lies eighth in the drivers' championship, one place and two points ahead of the Russian, who is understood to bring substantial backing to the team.
At the moment, Senna's race drive applies just to Spa and Heidfeld is said to be investigating legal channels to hang onto the driver for the remainder of the year.
