Substituted after 58 minutes of England’s 3-0 win against Wales on Tuesday, he embraced his replacement Callum Wilson and made his way to the bench to watch the remainder of the game.
England coach Gareth Southgate clearly thought the job was done and qualification to the knockout stage secured.
Kane, despite shaking hands with his coach, might not have shared that view.
For a man who is famously reluctant to sit out any opportunity to add to his scoring record, it was likely a frustrating watch from the sidelines at Ahmad Bin Ali Stadium.
Against a Wales team broken by goals from Marcus Rashford and Phil Foden, Kane was looking to finally get off the mark in Qatar. Instead, Rashford added a third of the match and his third of the tournament.
“He’s enjoying his football, but for any forward you want to be scoring goals,” Rashford said.
England scored nine goals as it topped Group B, but none came from its most prolific forward.
Yet Kane, who was the Golden Boot winner at the World Cup in Russia four years ago and is two short of Wayne Rooney’s all-time England record of 53 goals, has still made a notable contribution.
Providing the cross for Foden’s second-half strike, he became England's first player to register three assists at a World Cup since David Beckham in 2002. He can add to that total when England play Senegal in the round of 16 on Sunday.
“You need goals from all areas, and it is a problem for opposition teams if the threat is coming from other areas of the pitch,” Southgate said. “Across the three games pretty much all of our forward line has got off the mark — if not with goals then with important, quality assists and that’s a good place for the forwards to be. They want to have that confidence."
England's captain has always been a creator as well as a finisher and his assist statistics in his opening three games — also setting up goals for Raheem Sterling and Rashford against Iran — is evidence of just how complete a forward he is.
It also underlines his enduring importance to England.
Kane hurt his ankle and foot in the opening match against Iran, but Southgate has started the 29-year-old striker in all three matches.
“It is competition for places, which is what we need and people have to deliver,” Southgate said.
Goals aren't a particular concern for England, with Rashford, Bukayo Saka (two), Sterling, Jack Grealish and Jude Bellingham all scoring so far.
Rashford, who missed a penalty in England's shootout loss to Italy in the European Championship final last year, is the tournament's co-leading scorer alongside Kylian Mbappé, Cody Gakpo and Enner Valencia.
“In a long career, you’re always going to have ups and you always will have downs and it’s all about how you bounce back from them," Manchester United and England teammate Harry Maguire said after the Wales match. "I can’t speak highly enough about Marcus. He’s a wonderful man and he’s a great player and I think tonight again he’s shown that he belongs on this stage.”
