Brazilian Bruno Senna hoped to see out the Formula One season with Renault despite being confirmed for just two races while ousted German driver Nick Heidfeld mounts a legal challenge.
The 27-year-old nephew of the late triple champion Ayrton was handed Heidfeld's race seat for the Belgium Grand Prix on Thursday but no details were given about the terms of the deal.
Heidfeld also turned up in the Spa paddock wearing his Renault team kit and talking to the media and claimed he would be back in the number one drivers spot after the legal hearing takes place.
He refused to comment when asked when he had been told he would not be driving in Spa, whether it had come as a surprise and if he felt the decision had been more about money that anything else.
