Kovalainen appeared in the paddock at Silverstone this weekend just as it was in Bahrain and Barcelona
Jun.29 (GMM) Heikki Kovalainen is closing in on a return to the Formula One grid, Finland's well-connected Turun Sanomat newspaper reports.
But Kovalainen, who appeared in Friday practice for the green-clad team in Bahrain and Barcelona, is back in the paddock at Silverstone this weekend.
Turun Sanomat reports rumours the 31-year-old could be drafted back into Caterham's race lineup, at Dutchman van der Garde's expense.
Kovalainen said: "Nothing has been agreed, so do not try to guess.
"But I am ready to go in all respects, and yes I would rather be here to be racing than not," he added.
