Porsche have distanced themselves from reports that they have signed a deal with Mark Webber for 2014.
The Australian has been on a rolling one-year contract with Red Bull for the past few years, but his future at the team was thrown into fresh doubt following the Malaysian Grand Prix after team-mate Sebastian Vettel ignored team orders and claimed a controversial race win ahead of him.
Although Webber and Red Bull have rejected claims that he could walk away from the team this season, there have been rumours that he will join Porsche next year to lead their return on the World Endurance Championship and Le Mans 24 Hours.
However, the sportscar maker has denied the speculation.
"Mark Webber has not signed a contract with Porsche," Porsche's motorport spokesman told Sky Sports Online.
"In 2014 Porsche will return to Le Mans and the Sportscar World Championship WEC in the highest class LMP1. Our 10 factory drivers are an excellent basis for our driver line-up. If we will add additional drivers will be decided later this year."
