Ducati MotoGP chief Paolo Ciabatti is unsure of what role Casey Stoner will play with the manufacturer in the future as he needs to fully recover from a shoulder operation.
Stoner currently has only 90 degrees of movement after an operation and his contract as a test rider runs out at the end of this season.
"The situation is that, when we agreed with Casey to come back to Ducati as a test rider and brand ambassador, we had a 2 +1 – a 3 year deal – that is expiring at the end of 2018, so we, as you may know, we met Casey during World Ducati week at Misano and we spoke a bit about the future," said Ciabatti.
"He’s still recovering to the surgery to his shoulder and he still cannot really move his shoulder up more that 90 degrees, so it was quite a comprehensive surgery and he’s still rehabilitating from that.
"So we decided we would touch base again later, in September, and see what the progress is with the shoulder to see whether there are conditions to continue as it is now as a test rider and brand ambassador – or maybe only as an ambassador.
"We’ll have to see with him. I think his main concern now is to recover the use of his shoulder and arm. Once that is done we can talk about the future."
