Kubica testing in Merc simulator

Robert Kubica is testing with Mercedes on the team's race simulator as the Polish driver attempts a return to Formula One, according to a report.

The 28-year-old, who raced for BMW and Renault in F1, has been testing on the simulator at the team's works in Brackley, England, sources told German news agency dpa.

There was no official confirmation from Mercedes with whom Kubica carried out tests in the winter in the Germany-based DTM series.

Kubica's Formula One career was put on hold when he suffered life-threatening injuries during a rally crash in Italy in 2010. Although it remains to be seen if he will return to F1, he has taken part in the second-tier World Rally Championship this season.
