"The prognosis is good and he currently feels well, without any symptoms of being affected neurologically," commented the club.
The club explained that Sangalli, who was Real Sociedad's player of the month for October, was "waiting for the results of the tests which were carried out and this could take 2-3 weeks."
"Depending on these results more tests could be required and we will be able to make therapeutic decisions over the treatment."
The club added that for the moment the midfielder can "carry out a normal lifestyle, but without carrying out physical effort," and that for the moment "there is no date for him to return to his usual activity."
