James Tarkowski made his first appearance for the Clarets as a Burnley XI lost 1-0 to Oldham Athletic.
A strong Burnley side hosted two Latics first teams, each playing 45 minutes, in a behind-closed doors training match at the Barnfield Training Centre.
Oldham’s first team captain Liam Kelly scored the game’s solitary goal, with a 12th minute penalty proving to be the difference.
Paul Robinson played his second game behind an experienced back four of Tendayi Darikwa, Michael Duff, James Tarkowski and Christian Hill.
Fredrik Ulvestad and Michael Kightly also started alongside recent signing George Green in midfield, while Nathan Lowe - who was the only player not to play the duration - completed the midfield quartet.
Chris Long, who scored a stunning 35-yard strike in the Development Squad’s last outing, started up front alongside striker Rouwen Hennings.
And the German was adamant he had opened the scoring after just five minutes, when his 25-yard thunderbolt cannoned down off the crossbar, and appeared to be over the line.
However, despite the striker’s appeals, the officials waved play-on, and the Latics took the lead soon after.
Duff brought down Rhys Murphy in the area and Kelly rifled in the resulting spot-kick past Robinson, who had guessed the correct way.
The Clarets were then almost rewarded with a deserved equaliser as Hennings was once again denied.
Darikwa’s whipped cross in from the right was glanced to the far post by the former Karlsruher striker, for a brilliant diving save from David Cornell to keep the visitors ahead.
Two chances midway through the first half again went amiss for the Clarets, after a Kightly ball found Long at the edge of the box and his shot on the turn was never troubling Cornell.
Then, Hennings’ one-two with Long, after a Duff ball forward, ended with a fine volley from the German, which fizzed past the far post.
Lowe, who recently returned from a long-term injury then came close with the final kick of the half.
The midfielder’s 30-yard strike was low and bouncing, forcing a good save out of Cornell, who had to be alert.
And minutes after the restart the Clarets again came inches away from the equaliser.
Green’s effort from distance looked destined for the top right corner, only for the post to come to Oldham’s rescue.
Oldham had three Burnley connections featuring, with loanees Daniel Lafferty and Cameron Dummigan each playing 45 minutes, as did former Claret Joseph Mills.
And Mills also saw his shot shave the woodwork, with his bending free-kick from the edge of the box.
Substitute Brad Jackson almost brought the game level with his first touch, but his diagonal strike was well cleared off the line.
And the Clarets had one final chance of the game, but Ulvestad’s low drive was blocked, in turn setting up Hennings for a shot on the turn that bent agonisingly wide.
