Sean Dyche criticised the stewards for not acting more quickly to stop the Blackburn fan who confronted his players as the east Lancashire derby turned ugly at Ewood Park.
A supporter invaded the pitch after Jack Cork had headed Burnley in front in the 27th minute and grabbed Ashley Westwood by the throat before pushing James Tarkowski in the chest.
Dyche was unhappy that the offender was not apprehended until he had almost left the pitch with a second pitch invader, and admitted that he thought of intervening himself.
'When someone saunters on that slowly, it has to be dealt with because you just never know,' he said.
