Luke Shaw withdrew from the England squad for Sunday’s World Cup qualifier in Slovakia after missing training on Saturday morning.
The 21-year-old left-back has only just returned from double leg-break and has started the season well with Manchester United.
He was replaced in training at St George’s Park by Arsenal’s Tafari Moore, who is part of the Under-20s set-up, and did not fly with the team.
Shaw now misses out on a potential England return having last been capped almost a year ago in a 2-0 Euro 2016 qualifying victory over Switzerland at Wembley.
Speaking at that media conference, Allardyce said: “We just sent him back for precautionary measures. We made the decision just to send back to Man Utd and take no risks. He’s not injured, he just wasn’t feeling right.”
