Marcus Rashford is at risk of missing England's upcoming Nations League fixtures after he was forced off against Fulham.
The Manchester United forward was taken off during the second half at Craven Cottage on Sunday.
It comes less than a week before the Three Lions return to action for the first time since the World Cup.
Thomas Tuchel named his 27-man squad for the matches against Spain, Czechia and Croatia on Friday.
Rashford was amongst those included by the England boss after his bright start to the season.
However, he could now be forced to withdraw from the squad due to a potential injury blow.
The 28-year-old was replaced by Joshua Zirkzee in the 77th minute of United's 1-1 draw against Fulham.
His final contribution of the afternoon saw Rashford slip over prior to being withdrawn by Michael Carrick.
Rashford injury update
The Red Devils boss was unable to confirm the extent of the injury following the match.
When asked by talkSPORT's Alex Crook if there is a chance Rashford will have to pull out of the England squad, he said: "I really donâÂÂt know.
"As you can imagine, at the end of the game IâÂÂve spoken to the players and not really got to that stage. So weâÂÂll just have to wait and see."
England face Spain at Wembley Stadium on Saturday, September 26 as they begin their Nations League campaign, live on talkSPORT.
Rashford featured six times for the Three Lions at the World Cup in the summer.
He ended the tournament with one goal and one assist as Tuchel's side finished third, their best performance since 1966.
Meanwhile, he has made six appearances in all competitions for United so far this season.
It follows his return to the fold after loan spells with Aston Villa and Barcelona.
Rashford has featured in all five Premier League matches this term, starting the last four.
However, he has yet to score or provide an assist during the current campaign.
Sunday's visit to Fulham saw him draw a blank once again, with the Red Devils rescuing a point late on.
Matheus Cunha's equaliser cancelled out an own goal from Lisandro Martinez to leave United 12th in the table.
