FA chief executive Mark Bullingham has admitted there is a "very real" threat of Harry Kane being given a yellow card for wearing the One Love armband.
The Football Association are seeking clarity from FIFA over whether they will be punished for making the anti-discrimination gesture. England are one of nine nations to sign up to wear the rainbow armband which is supposed to promote diversity at the tournament.
England captain Kane said he wants to wear it but, with just hours to go before the Iran game, there is still uncertainty over whether they will get punished with a fine or a yellow card. FIFA have threatened “sporting sanctions” which could mean a yellow card. Two yellow cards in the Group would rule Kane out of the final Wales game.
