Burnley have "strongly condemned" supporters who threw objects and attempted to invade the pitch during their match with Manchester City.
City defender Rico Lewis was struck by a lighter thrown from the crowd while another fan was restrained after they tried to get on to the playing area.
The incidents occurred at last Friday's Premier League opener at Turf Moor.
"Both fans were identified and removed from the ground. Both now face severe banning orders," said a club statement.
"Burnley strongly condemn the unacceptable behaviour of items being thrown and the invasion of the pitch by some of our supporters.
