The other 25 players of Gareth Southgate’s squad trained normally at St George’s Park ahead of the Euro 2020 final on Sunday night against Italy at Wembley.
The entire 26-team passed UEFA-mandated coronavirus PCR tests before the match.
Foden, 21, has made three Euro 2020 appearances so far and came on in overtime in the 2-1 semi-final win over Denmark, replacing Mason Mount.
The Manchester City academy product, who has represented his country since U16 level and won the U17 World Cup four years ago, made his debut for the senior national team last September against Iceland in the UEFA Nations League.
He excelled last season, scoring 16 times and providing 10 assists in 50 games in all competitions under Pep Guardiola, as City won the Premier League, the EFL Cup and reached the Champions League final.
Foden’s form saw him selected by Southgate for the Euro 2020 final and the playmaker performed well in England’s first 1-0 win over Croatia.
After receiving a yellow card in that game, Foden played against Scotland but was later put to rest by Gareth Southgate for the Czech Republic clash and was an unused substitute for the knockout stage wins direct against Germany and Ukraine.
England face Roberto Mancini’s Italy at Wembley in the final on Sunday, where around 60,000 fans will watch at the national stadium.
Foden: England will play the game, not the opportunity
In the run-up to Sunday’s centerpiece, Foden warned his teammates not to be fazed by the atmosphere and hype surrounding England’s first final appearance in a major tournament since 1966.
“There is going to be so much emotion for the final with all the fans out there,” Foden said on the official English podcast.
“But as players we just have to stay focused and treat it like it’s the first game of the tournament.
“We don’t need to change anything because we’ve been brilliant in every game and (hopefully) we can cross the line.
“Reaching the final in our stadium with the fans behind us is just an amazing feeling.
“And being the first England team to reach the European Championship final shows how special the team is and how hard we have worked.
“It was difficult without seeing our families as much as usual, but we are so happy to have reached the final and I think that is what we deserve.
“We know we have a very difficult final ahead of us, but we’re all excited. “
