Southend United have disciplined defender Bilel Mohsni, amid reports of a 'fracas' at the club.
Mohsni missed the weekend trip to Accrington and was on the bench in Tuesday's defeat at Crawley.
Manager Paul Sturrock told BBC Essex: "His whole demeanour at this minute in time is something I'm going to have to look into.
"He has been internally disciplined for the fracas the other night. We are going to have to sort something out."
He added: "His actions have let himself down, anyone would feel that this is his last opportunity."
The Tunisian centre-back was left out of the squad for Saturday's win at Accrington, with the club citing the fact that he was observing Ramadan as the reason.
It has since emerged that Mohsni has been disciplined by the club for his behaviour last week.
Mohsni was plucked from the French lower leagues to join the club last summer.
