Schumacher had signed up to be a test driver for an Italian kart maker.
Jan.28 (GMM) Now back in retirement, Michael Schumacher will return to his karting roots in 2013.
Spain's El Mundo Deportivo newspaper reports that the great German will in fact be racing in 2013.
Preparing for his new race seat in the KZ category, Schumacher was testing his Tony Kart at the Lonato circuit in Italy last week and - reportedly - his laptimes were "very good".
Meanwhile, the Kolner Express newspaper reports that - with Hermann Tilke on board as designer - Schumacher has commissioned a new world championship-standard karting circuit near Cologne.
"We will build the best track in Europe," Gerhard Noack is quoted as saying.
Tilke confirmed: "The plans are ready."
