Renault has confirmed the news that Nick Heidfeld will be replaced by test driver Bruno Senna, although the team has only announced that the Brazilian will be in race seat for this weekend's race at Spa.
In an interim statement released on Wednesday night, the team confirmed that Senna will partner Vitaly Petrov for the Belgian Grand Prix and will attend the FIA's official press conference on Thursday afternoon.
A further statement confirming more details about the move is set to be released by the team later this morning.
Senna's move back into a race seat for the first time since the 2010 season finale could mark the end of Heidfeld's F1 career with limited options available for the experienced German racer elsewhere in the paddock.
Understandably, Heidfeld is reported to be far from happy at being ousted from his drive having joined the team at the start of the season to replace the injured Robert Kubica, especially as he has so far outscored team-mate Vitaly Petrov.
Senna could now be in line to drive for the remainder of the season or Renault may decide to use some of the final races of the year to give Romain Grosjean time on track, with team boss Eric Boullier making no secret of his desire to see the GP2 racer back on the F1 grid.
Grosjean could wrap up the GP2 title this weekend at Spa if results go his way and would then be in a position where he could turn his focus towards F1.
