Southampton have suspended club record signing Dani Osvaldo for two weeks, following an incident at the clubs Staplewood training ground, according to BBC Sport.
The Italian international became the clubs record signing when the Saints paid Roma a fee of £14million for his services in the summer.
The club has not released any details about the nature of the incident.
A Saints statement read: “The club has taken swift and proper action for what it considers a breach of the conduct expected of its players.”
Earlier this month, Osvaldo was given a three match ban and fined £40,000 by the Football Association, for his part in a touchline fracas during the draw with Newcastle at St James’s Park in December.
He is set to miss the Saints FA Cup tie with Yeovil, as well as the Premier League clashes with Fulham and Arsenal.
Osvaldo has failed to settle since his summer arrival at St Mary’s, managing just three goals in 13 Premier League appearances this season.
The 28-year-old has already been linked with a return to Italy, with Inter Milan reportedly keen on signing him this month.
