UPDATE: Movistar Yamaha has issued the following statement:

'Having ridden his first laps around the Misano World Circuit Marco Simoncelli yesterday, Movistar Yamaha MotoGP's Valentino Rossi was back aboard his YZF-R1M today at 3:30pm (GMT+2) to resume his physical test.



'During the two-hour private riding session the nine-time World Champion was able to complete 20 laps in total. He wrapped up this second day of testing with an improved feeling and a more positive impression compared to yesterday.



'Tomorrow Rossi will undergo a medical examination - to verify the positive rehabilitation progress experienced in today's session - after which he will make a final decision on his attempt to take part in the Gran Premio Movistar de Aragón.

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

After a brief rain-shortened test on an R1 Superbike at Misano on Monday, injured MotoGP star Valentino Rossi returned to the circuit on Tuesday.

According to Rimini Today , the Italian has so far been able to put in around a dozen laps as he seeks to understand if his healing leg has recovered enough for an early comeback in this weekend's Aragon Grand Prix.

Rossi broke his right tibia and fibula just 19 days ago and is to make a final decision on Aragon by Wednesday evening.

If Rossi does not attempt to ride, WorldSBK star Michael van der Mark is on standby to take his place.
