Valentino Rossi will wait until Wednesday before deciding whether he is fit enough to make his MotoGP return at this weekend's German Grand Prix.
The world champion had a second test on a Yamaha Superbike at Brno today to assess the progress of the leg he broke in a practice crash at Mugello in early June.
He completed 46 laps, with a best time of 1m59.135s - one second off the pole times from last weekend's World Superbike rounds, but quicker than the fastest race laps.
Rossi had initially been expected to announce his decision regarding the Sachsenring race immediately after today's test, but will now have a further medical check on Wednesday before making his mind up. He will then need to get official medical clearance to participate in Germany.
"Yamaha awaits Valentino's final personal decision as to when he feels ready to ride again," said a team statement.
"Yamaha's priority is a full recovery to fitness for Valentino rather than a quick comeback."
Rossi said he had enjoyed the Superbike run, but still had some fitness concerns.
"Today was good, I felt better than in Misano but I still feel quite tired after a few laps and a race will be a much bigger question," he said.
"We haven't made the final decision yet, I need to have some more x-rays on Wednesday and then my doctors and I will consider whether I can ride at Sachsenring.
"Once I'd understood my physical condition today, I had great fun riding the R1 and even did some work on the settings/ I want to say a big thank you to the WSB team for staying on here another day and making this test possible for me."
Yamaha test rider Wataru Yoshikawa will stand in again if Rossi chooses not to race in Germany, and is travelling to the Sachsenring in readiness in case he is needed.
