Key England figures Reece James and Declan Rice did not participate in the team's final training before their crucial World Cup group stage match against Panama, raising injury concerns.
The Three Lions returned to their Kansas City training base after a goalless draw with Ghana, but two key players were absent from Thursday's session.
The match against Panama, the last in their group, will be played at MetLife Stadium. Reports indicate that 26-year-old James sustained a hamstring strain during Tuesday's clash with Ghana.
Now, head coach Thomas Tuchel faces a significant challenge regarding the Chelsea player's fitness for Saturday's encounter. Even if available, James might be rested after playing two matches within a week.
This could open up an opportunity for Jarell Quansah or Jed Spence to start at right-back, while Nico O'Reilly would likely fill the left-back position.
Declan Rice's situation appears less concerning. The 27-year-old Arsenal midfielder was seen with a bandage on his left calf after the draw with Ghana. This marked his 64th game in an incredibly demanding season, and he reportedly sustained a muscle strain.
Rice is ready to start if needed. However, similar to James, he might also be rotated against the Panama squad, currently ranked 42nd in the world.
Another factor is that Rice received a yellow card against Ghana. Another booking in the final group stage match would mean he would be suspended for the Round of 16.
