are working with Lancashire Police after footage emerged of both sets of supporters involved in a fracas following a crucial win over relegation rivals Cardiff
The video looks to have been recorded from a supporters' coach with one fan seen lying flat on the pavement, after apparently being knocked unconscious on Harry Potts Way after hitting his head on a wall.
Lancashire Police and Burnley are aware of the incident but have not been made aware of any serious injuries.

Emotions were running high between the two sets of supporters and the video shows that they were not kept apart leaving the ground.
A Burnley statement read: 'Burnley FC is aware of a post-match incident involving two sets of supporters outside Turf Moor after Saturday's game with Cardiff City.
'In addition, a number of offensive posts have been reported to the club, and we are working with Lancashire Constabulary on both these issues.'
Burnley fans toasted a crucial win against a relegation rival as they all-but secured survival in the Premier League with the 2-0 home win.
Two goals from Chris Wood sealed what became a controversial victory after Cardiff saw a penalty award, following a handball from Burnley's Ben Mee, overturned with the score at 1-0.
Victory took Burnley to 39 points and 11 points clear of Cardiff with five games remaining.
Neil Warnock's Cardiff side play their game in hand against beaten FA Cup semi-finalists Brighton on Tuesday night, needing a win to give themselves any hope of survival.
