Hulkenberg has been axed by Renault for the 2020 F1 season; with Esteban Ocon joining the French team from Mercedes in his place. There were rumours the Hulk would move to Haas and replace Romain Grosjean.
However, on Thursday morning it was announced that Grosjean would retain his Haas seat for next season and partner Kevin Magnussen once again, meaning a drive for the American outfit was off the cards for Hulkenberg (for now, anyway!).
Brown, the McLaren motorsport chief executive, "approached" Hulkenberg over driving in IndyCar for next season, but it appears the German driver does not want to drive in that form of motorsport at the moment.
It could be a case of the waiting game for Hulkenberg and see if anything becomes available at Red Bull, with the Milton Keynes-based squad far from certain about their future drivers just yet.
Williams have also just had a seat become vacant with Robert Kubica announcing his departure from Formula 1; but deputy team principal Claire Williams revealed the team have not approached Hulkenberg about the seat.
