DRIVING legend Michael Schumacher has called off his Formula One comeback due to concerns over a neck injury.

Schumacher, a seven-time F1 world champion, had agreed to help out former team Ferrari and step in for Felipe Massa on a temporary basis after the Brazilian suffered head injuries at the Hungarian Grand Prix last month.

But the German has now abandoned the comeback after failing to shrug off an injury suffered in a motorbike accident in February.
