The 26-year-old midfield maestro is set to undergoing further evaluation at the Italian Serie A outfit.
The club released the following statement on their official website:
“Acquah reported a sprained trauma to his left knee.”
“The instrumental investigations carried out at the Fornaca clinic have excluded important meniscal or ligament injuries.
“For the purposes of recovery, the clinical evolution will be evaluated.”
Should the injury demand a significant layoff period, Acquah may miss next week’s clash with Cagliari after the international break.
Acquah and his Ghana’s team-mates will face Iceland in an international friendly match in June, 2018.
