A dejected Michael Schumacher described his aborted return to Formula One as his "toughest moment" after a neck injury left him unable to drive for Ferrari in the European Grand Prix as a replacement for Felipe Massa. The seven-time world champion told a televised press conference on Wednesday that he was so disappointed that he was unable to even think about reviving his comeback hopes later this season. Massa, who suffered serious head injuries in a qualifying crash at the Hungarian Grand Prix, is set to be sidelined for at least four races, with test driver Luca Badoer now drafted in for the next grand prix in Valencia next week.
