England manager have reportedly also made a decision on Mason Greenwood as police continue to investigate claims of rape.
Greater Manchester Police on Wednesday announced that the 20-year-old was released from custody on bail pending further inquiries after being arrested on suspicion of rape.
Man United have already announced that Greenwood will not train or play with the club until further notice.
The Sun have now reported that Southgate has also taken the decision to banish the striker until all legal proceedings are concluded.
United interim manager Ralf Rangnick broke his silence on the matter ahead of the FA Cup clash with Middlesbrough.
"We had a good normal week of training with five training sessions including today's training, obviously it was a topic within the team but they're human beings and Mason was part of the group before we had our break," Rangnick said, as per the Sun.
"It was a good week of training, we could train under normal circumstances and we are looking forward to the game tomorrow."
