Sauber are set to replace driver Pedro de la Rosa with German Nick Heidfeld for the remainder of the 2010 season, the BBC reports.
It is thought that Heidfeld, who began the season as Mercedes test driver and was released to test tyre for Pirelli, will be in the C29 at Singapore on 26th September, and for the following four races.
De la Rosa, returned to racing this season after three years as a test driver, has scored just six points this season, 15 less than rookie teammate Kamui Kobayashi.
It was confirmed last week that Kobayashi would be retained by Sauber in 2011, but the statement did not say anything about de la Rosa’s future.
A Sauber spokesman, speaking to the BBC, said “[Team principal] Peter Sauber is not making comments about drivers at this time.”
Heidfeld raced for Sauber for three seasons from 2001-2003 before leaving for Jordan and then Williams. He returned to Sauber as BMW took over in 2006, and left the team when the German car giant exited the sport. The German, who is yet to win an F1 race, has scored 188 of his 219 career points over the seven season he has spent with the team.
He also holds the record as the highest F1 points scorer without a win, the driver with the most number of career podiums (12) without a win, and for the highest number of consecutive race finishes (33).
