"There has been a bit of a setback," the 32-year-old told MUTV.
"We had a look at it but it was not really anything to do with the old injury, other than it will take a few more weeks to recover.
"The specialist is very pleased with how the old injury is progressing, so I am hoping to be back in training by November 1."
Where he'll fit into the team or in Queiroz talk 'system' is anyone's guess.
