Wigan have banned more than a dozen fans as a result of incidents during last weekend's derby victory at Bolton.
A number of flares were set off in the Latics end at the Reebok Stadium and the club have responded by writing to 17 spectators, predominantly aged between 15 and 22, to inform them they are no longer welcome to attend matches.
"We were extremely disappointed by the behaviour of a small minority of spectators who tarnished what was a fantastic day for the club," Wigan chief executive Jonathan Jackson said in a statement.
