Tottenham boss Antonio Conte says Harry Kane is "really, really tired" after he was replaced in the second half of a Carabao Cup loss at Nottingham Forest.
England boss Gareth Southgate names his squad for the World Cup on Thursday.
"It was a problem of tiredness," said Conte, who stressed Kane would be OK. "It's only fatigue but it's normal because Harry played every game."
Kane made his 21st consecutive start for Spurs in the EFL Cup third-round match at the City Ground on Wednesday evening.
He was replaced after 59 minutes despite Spurs trailing by two goals, with Forest earning the win through strikes by Renan Lodi and Jesse Lingard.
