A 2-1 win for Leeds United at Brentford kept them up at the expense of the Clarets, who slumped to a final day defeat at home to Newcastle United.
It means Burnley, who had been temporarily led by former Seasider and Lilywhite’s defender Mike Jackson, finished the season on 35 points, three points behind Jesse Marsch’s Whites.

The last time all four of those Lancashire clubs were in the same division was way back in the 1960/61 term — the season after Harry Potts’ Burnley had been crowned champions of England for the second time.
Burnley finished fourth in the First Division that year with Blackburn in eighth and Blackpool 20th.
Preston, however, were relegated that season, their first without Sir Tom Finney, and the four clubs have never reconvened since.
The last time Burnley met either side in a competitive fixture was in August 2017, when first half strikes from Jack Cork and Robbie Brady silenced Ewood Park during an EFL Cup tie against Rovers.
Joey Barton netted the only goal of the game when the Clarets last faced PNE as his deflected free kick in the sixth minute wrong-footed goalkeeper Chris Kirkland and sent the visitors well on their way to a Premier League return.
Burnley’s most recent meeting with Blackpool was also pivotal in their previous promotion push from the Championship under Sean Dyche.
A Michael Kightly goal gave the away side a 1-0 victory at Bloomfield Road in April 2014.
Who’ll claim the bragging rights when the quartet go head-to-head in a long-awaited battle this time around?
