Nick Pope saw his hopes of a Golden Glove dashed as Brighton & Hove Albion forgot to read the sentimental script.
Burnley were seeking a 16th clean-sheet for their stopper but a stunning early strike from Yves Bissouma quickly dashed those plans.
A later goal from Aaron Connolly cancelled out Chris Wood's equaliser and Burnley slumped to a final day defeat despite a battling performance.
The Clarets were unchanged from their 2-0 victory against Norwich City but Brighton made three changes from their draw with Newcastle United. Pascal Gross, Leandro Trossard and Aaron Mooy were replaced by Solly March, Alexis Mac Alister and the goal-scorer Conolly.
Story of the match
The visitors made a bright start but they were facing a stern Burnley defence who had extra fire in their belly with Pope's award on the line. It was fitting, therefore, that the opening goal was a thing of beauty.
Wood's half-clearance was seized upon by Bissouma and the midfielder curled home a sublume effort from 25-yards. Pope dived full length but was unable to keep the ball out.
It was a goal that turned the tide for Brighton and they started to gain the ascendancy.
Neal Maupay rattled the crossbar with a header from close range and young Lamptey was showing lots of attacking energy. Nonetheless, Burnley fought back.
Erik Pieters was the provider with a beautifully weighted pass for Wood. The striker latched onto the ball with his right foot and finished the ball with his left. A fine goal.
It was a quick start for the visitors and they caught Burnley out at the back. Maupay played in Connolly and the 20-year-old powered past Kevin Long before slotting past Pope.
The Clarets were stung by that quick goal but Connolly's strike awoken the beast.
Jay Rodriguez thought he had equalised with a glancing header but Johann Berg Gumundsson, positioned in-line of Mat Ryan, was offside and adjudged to be interfering with play. Goal ruled out.
Lewis Dunk made a stunning block to deny a rocket from Long who found himself in an unorthodox attacking position in the box.
Wood later saw a close-range header blocked on the line as Burnley really piled the pressure on but it wasn't enough in the end.
A competitive game where both teams played with the shackles off. Both setups will welcome a much needed break after this hectic schedule. Burnley will hope that their manager is still around after that break.
Burnley: Pope 6; Bardsley 6, Long 6, Tarkowski 6, Pieters 6; Gudmundsson 6, Westwood 7, Brownhill 6, McNeil 7; Wood 7, Rodriguez 6.
Subs used: Vydra 6, Brady n/a.
Brighton & Hove Albion: Ryan 6; Lamptey 8, Webster 7, Dunk 7, Burn 6; Bissouma 7, Stephens 6; Connolly 7, Mac Allister 6, March 6; Maupay 7.
Subs used: Bernardo 6, Propper 6, Mooy 6, Jahanbakhsh n/a, Murray n/a.
Chris Wood: A really tidy finish for his 14th goal of the season. He is a real handful for defenders and his goal-scoring speaks for itself.
Tariq Lamptey: Another really impressive display by the youngster. Confident and assured performance.
There was a huge desire for Pope to win the Golden Glove but those aspirations quickly unravelled. A tight and resolute Burnley defence became a little more slack after Bissouma's outstanding goal but that was to be expected. It was the last game of the season and it had very little riding on it.
Going to close will hurt Pope but it shouldn't have any lasting effects. His reputation has soared this season and many people are seriously talking about him being England's number-one goalkepeer. That will matter to him more than the individual accolade.
Tariq Lamptey has the potential to be something very special. He is confident at bombing forward and also possesses some good defensive instincts.
The 19-year-old came through the Chelsea academy and is very unforunate to have been shadowed by Reece James. James has phenomenal ability and has burst onto the first-team scene at Stamford Bridge. As a result, Lamptey was allowed to leave but this is a player with a very bright future. Leaving the Londoners will have been a setback but it might not be long before the big clubs are courting his services.
It must be said that Brighton are a fine fit for Lamptey. Graham Potter wants to play a progressive style of play and he is clearly a manager that wants to give young players an opportunity.
