The two-time world motorcycling champion Casey Stoner will call it quits on his V8 Supercar experiment at the end of the year, and is set to take a break from all motorsport in 2014.
The Australian, who has been racing in the second-tier V8 series this year for Red Bull Racing, says he will end his brief flirtation with car racing at the end of the season.
But the prospect of the 27-year-old returning to MotoGP in 2014 appears remote.
The most likely scenario is Stoner will take 12 months off, and any return to the sport in which he won two world championships before his shock retirement last year would have to wait until at least 2015.
