The Daily Mail reports it is understood that Sterling attempted to grab Gomez by the neck following his arrival in the players' canteen at St George's Park on Monday, the day after they clashed during Liverpool's 3-1 win over Manchester City.
The FA have confirmed that Sterling would not be considered for selection against Montenegro on Thursday as a result. The 24-year-old will stay with the squad however and could play against Kosovo on Sunday.
Sterling was sat down in the canteen when Gomez arrived and leant over from behind to shake his hand, leading to him to attempt to grab his team-mate by the neck. The rest of the England players initially thought Sterling was joking, but it soon became clear that he had lost control and the pair were separated.
The incident was particularly surprising to the other Liverpool players present as Sterling and Gomez had made the peace following the game at Anfield with an embrace following the final whistle. The cause of Sterling's eruption was unclear, although England sources were speculating on Monday night that he may have reacted badly to being widely lampooned on social media for coming off second-best physically in the initial confrontation with Gomez.
