Italian Serie A side Empoli have announced that midfielder Afriyie Acquah suffered a flexor injury during their clash against Sassuolo on Friday.
The Ghana international was substituted after 14 minutes in the 3-1 defeat due to pains in his thigh.
Acquah underwent a scan and it has been revealed a contraction of the muscles.
He has played in all five league matches since joining Empoli on transfer deadline day on loan from Torino.
