Eriksen, 34, appeared to grab his chest before falling to the ground during Denmark’s pre-World Cup friendly against Ukraine on Sunday (June 7). The game was later abandoned.
This is the second time the midfielder has collapsed on the pitch due to a heart problem, he was fitted with a implantable cardioverter-defibrillator device after suffering a cardiac arrest at Euro 2020.
Speaking to ITV Sport, former Tottenham ace Kane revealed he reached out to Eriksen in support.
“I’ve reached out to him (Eriksen) today”, he said.
“The main thing is the defibrillator was there and it worked.”
He added: "I've not heard nothing back from Christian yet, but obviously he put the statement out saying he will go away and rest up and spend some time with the family now, which I think is important".
Kane then admitted Eriksen “has some decisions to make” about his future.
