Norwich City are reportedly looking into allegations of racist behaviour from a handful of their supporters during Sunday's opener against Wolverhampton Wanderers.
An incident is believed to have occurred in the away section of fans during the Canaries' 1-0 defeat at Molineux in the Championship.
The club have told Sky Sports News that any supporters found guilty of racist behaviour could be handed a lifetime ban from attending matches.
Norwich were demoted from the Premier League to the second tier of English football at the end of last season.
