The Tyree, now 19, returned to training after his three-week holiday, but the youngster was a few hours shy of returning to full training on Wednesday, after missing training on Friday due to illness.

Tyree, who was playing for the Under-19s at the time of the accident, was not injured during the incident.

“Tyree is fine, he just had a fever and he went home to bed,” said England head coach Eddie Jones, who is keen to continue the progress of Henry.

The Under-21 international, who scored in England’s 2-0 friendly win over Denmark on Tuesday, will not miss England’s next two matches in Group D and the final two matches of the Under 16 European Championship, as well as the World Cup qualifiers against Belgium and Iceland.

He has not yet been diagnosed with any long-term injury.

A number of players have been included in England squads for the matches against Denmark and Ireland, and it is understood that the England squad is still being developed as part of the medical process.

On the subject of Henry, Jones said: “He is a fantastic player and I know he will be back to full fitness.”

Henry had a knee operation last week after tearing his anterior cruciate ligament (ACL) during England’s pre-World Cup warm-up, but is expected to be fit to face England.

Meanwhile, England will face a tough qualifying group for the European Championship.

They will be joined by the Republic of Ireland in the group stage, followed by the Czech Republic, the Netherlands and Germany.
