Michael Schumacher said Tuesday, Aug. 11, 2009 he is calling off his much-anticipated Formula One comeback because of lingering injuries from a motorcycling crash earlier this year. The seven-time world champion was to fill in for injured Ferrari driver Felipe Massa and hoped to return at the European Grand Prix in Valencia, Spain, later this month. (AP Photo/Ralph Koehler, File)
