Rosberg absent at Spa on Thursday

(GMM) One regular face missing from the Spa-Francorchamps paddock on Thursday was Williams' Nico Rosberg.

The 23-year-old German was apparently still in England, where at the Silverstone circuit he was completing a final shakedown at the wheel of a Toyota-powered FW30.

Normal testing is banned on the week of a grand prix, but teams are allowed to complete up to 50kms for preparatory running.

Rosberg's task on Thursday was, nonetheless, unusual — especially given the fact that Nico Hulkenberg is the British team's regular test driver.
