Williams have denied reports that Robert Kubica is definitely returning to Formula 1 with the British team next year.
Earlier, multiple authoritative sources said thatthe Pole's comeback has now been definitively agreed, with Kubica perhaps having signed a two-year deal.
However, a Williams spokesperson told GMM: "Although conversations are ongoing with Kubica, it is still yet to be finally decided who will replace Felipe Massa.
"We will make an announcement when we have something to announce but nothing is planned this weekend in Abu Dhabi."
Kubica last raced in F1 in 2010.
