Yamaha rider Valentino Rossi was back in action for the second day running today as he attempts to assess hi fitness levels ahead of this weekend's Aragon GP.

Having ridden his first laps around the Misano World Circuit Marco Simoncelli on  Monday in a session that was cut short by rain, Rossi climbed back aboard his YZF-R1M on Tuesday at 3:30pm (GMT+2) to resume the test.

During what was a two-hour private session, The Doctor completed a total of 20 laps, wrapping up this second session with an improved feeling and a more positive impression compared to Monday.

Later today Rossi will undergo a medical examination in order to verify the positive rehabilitation progress experienced in Tuesdays session, after which he will make a final decision on whether or not he will part in this weekend's Gran Premio Movistar de Aragón.

A further update will be given after the Italian's check-up.
