Nuerburg, Germany - Toyota's Timo Glock will start from the back of the grid in Sunday's German Formula One Grand Prix after stewards Saturday imposed a penalty for a training incident.

Glock was penalized three places but effectively moves from 19th to 20th and last in the starting line-up for the race at the Nuerburgring.

Stewards ruled that the German hindered Renault driver Fernando Alonso of Spain in the first of the qualifying rounds. The decision means that Sebastien Bourdais of France in a Toro Rosso moves up one place to 19th. (dpa)
