Ezri Konsa and Nico O’Reilly are both doubts to play in England’s Nations League match against the Czech Republic on Tuesday night.
The pair were the only two members of the England squad to miss training on Monday morning, with the players following their own individual programmes.
Both played the full 90 minutes in England’s 3-2 loss to Spain on Saturday.
Manchester City’s O’Reilly started at left-back, a position he made his own during the World Cup, and his absence would open an opportunity for Lewis Hall to play.
It was O’Reilly’s mistake which led to Alex Baena drawing Spain level at 2-2 at Wembley before the World Cup winners went on to claim victory.
Arsenal centre-back Konsa has become one of Tuchel’s most trusted players and started seven of the eight matches at the World Cup.
Central defender Jarrad Branthwaite came on for Marc Guehi late on against Spain and could be a contender to start if Konsa is unavailable.
England play four matches in this international window and, after the loss to Spain, take on the Czech Republic both home and away, either side of travelling to Rijeka to play Croatia.
