UPDATE: Valentino Rossi tests at Misano!

UPDATE 2: Movistar Yamaha has confirmed Rossi's surprise test - CLICK HERE.

UPDATE: According to Rimini Today Valentino Rossi briefly tested an R1 road bike at Misano on Monday afternoon, just 18 days after his training accident, to avoid the bad weather forecast for Tuesday.

But the Italian star is reported to have completed just 4 laps of the circuit before rain arrived.

Rossi's Aragon intentions currently remain unknown, with Yamaha yet to officially comment on the test...

Valentino Rossi's impressive rate of recovery may have prompted the Italian to schedule a test at Misano this week, using a road bike.

According to several Italian sources, including GPOne.com, The Doctor is considering trying an R1 (or R6) bike at the circuit on Tuesday.

Yamaha have been asked about the reports, but are yet to respond.

If true, the test would mean the nine-time world champion is considering an early MotoGP comeback at Aragon this weekend.

But unfortunately for Rossi, who would need dry track time to understand the strength in his healing leg, bad weather is forecast for Misano on Tuesday and it remains to be seen if the test will happen.

Rossi suffered displaced (non-aligned) fractures of his right tibia and fibula in an enduro training accident on August 31, undergoing surgery the following day and missing his home Misano round.

Doctors estimated he would need 30-40 days recovery. Aragon would be only 22 days and - upon confirming that WorldSBK star Michael van der Mark is due to take Rossi's place this weekend - Yamaha Racing managing director Lin Jarvis said it was 'virtually impossible' for the Italian to be fit.

Nonetheless, the injury is described as less serious than the compound (bones piercing the skin) leg fractures in 2010, for which Rossi was out of action for 42 days.

Jarvis made clear that, just as in 2010, Rossi would test his strength on a road bike before attempting a MotoGP comeback - hence the clear signal of intent should Rossi ride such a bike this week.

Rossi remains fourth in the world championship but has now dropped 42 points from joint title leaders Marc Marquez and Andrea Dovizioso, with five rounds and a maximum of 125 points still available.

Yamaha, which did not replace Rossi at Misano, are contractually obliged to do so if the #46 cannot ride at Aragon.
