The young Clarets looked to have claimed their first victory since January until a late Sheffield Wednesday equaliser denied Danny Cadamarteri’s side all three points and second spot in the table.
Burnley – without a win in their previous five games – took the lead through Sam Layton before Preslav Borukov pulled the Owls level just before the break.
Winger Tristan Jumeau (main picture) restored the Clarets’ lead with his sixth goal of the season with just over an hour gone but six minutes from time in-form Wednesday struck again to extend their run to just one defeat in eight games.
The Clarets started brightly and twice went close through Will Harris and Terry Mupariwa before Jumeau missed a decent chance when he dragged a shot just wide.
Burnley did go in front when midfielder Layton (above) powerfully headed in his second goal of the campaign from Jordan Barnett’s corner with 35 minutes gone.
But the lead didn’t last long, Bulgarian forward Borukov heading past Aiden Stone to make it 1-1 a minute before half-time.
Burnley again started on the front foot following the re-start and restored their advantage when Jumeau delightfully dinked the ball into the back of the net from 25 yards out to claim his first goal since October.
The Clarets could have another when substitute Marley Blair curled an effort just wide of the post.
Stone then made an outstanding save to preserve the lead but the Clarets’ keeper couldn’t keep the home side out as a late scramble brought Wednesday the goal and the point that lifted them to third spot in the U18 Professional Development League’s northern group.
Burnley: Stone, Cropper, Wilson, King, Mpofu, Moss, Layton, Mupariwa (Ellison 57), Jumeau (Blair 64), Barnett, Harris (Yari 82).
