Kubica has not raced in Formula One since 2010 with Renault and was set to race in 2011 however in February of that year the Polish driver suffered severe injuries in a rally crash which resulted in Kubica having to stop racing in Formula One.
Williams have recently been working with Kubica to whether or not a return to Formula One is feasible for the Pole.
Former Toro Rosso driver Daniil Kvyat has also emerged as a candidate for the drive alongside Lance Stroll having been dropped by Red Bull in recent weeks.
