In the game of football it is a norm for a team to wear a black band or observe a minute silence before kickoff so as to acknowledge and mourn their loss. In the game between Nigeria and Argentina it wasn't so, now the question is what could be the possible reasons? Could it be that FIFA refused to allow Nigeria acknowledge their bereaved so as to avoid political interference in the competition or super eagles of Nigeria were nonchalant about it and feel it isn't necessary?

FIFA doesn't allow those stuff anymore
but the English fa is just too stubborn to listen so there use it only in their tournaments

You're right,
Fifa bans players from wearing political, religious or commercial symbols and the FA has previously been challenged over UK teams choosing to wear poppies near to Remembrance Day.
