The Norwegian Football Federation is considering filing a formal complaint to FIFA’s ethics committee about the decision to suspend Folarin Balogun’s automatic one-match ban during the World Cup.

United States forward Balogun was expected to miss his side’s last-16 tie against Belgium after being shown a straight red card during their 2-0 win over Bosnia-Herzegovina.

But, after an intervention from US President Donald Trump, the one-match ban was suspended for 12 months. No reason was given, beyond citing a rule that allows punishments to be suspended.

Balogun started the match, which Belgium won 4-1.

In a statement provided to the BBC, NFF President Lise Klaveness said the federation had reacted with “strong concern” and a decision on whether or not to make a complaint would be made at its next board meeting.
