Striker Sam Vokes will continue his comeback tomorrow - but Clarets boss Sean Dyche feels a first team return at the weekend is unlikely.
Vokes has had two run outs for the development squad, as he reaches the end of a long road back from a cruciate knee ligament injury sustained at the end of March.
He scored against Carlisle United in a 45-minute outing, before netting a double at Sheffield United as he completed 70 minutes last Wednesday.

But, asked whether the Southampton fan could be back in contention to face his boyhood team, Dyche admitted: “I doubt it but we’ll see.
“It’s important that he’s ready, and forget about when I think he’s ready, it’s important that he’s ready.
“We’re not putting the reins on him, it’s just when he’s ready.
“You never know, that’s why I said it’s important that he’s ready, managers and coaches can make decisions too early, you can leave them too late.
“I always think the players know when they’re ready, I certainly did when I was a player, I wasn’t as talented as him but I had a good mentality and I knew when I was right and ready.
“He’ll know and when he’s ready he’ll let me know.”
Meanwhile, Dyche revealed left back Stephen Ward suffered a fractured ankle against Newcastle United last Tuesday night.
Ward took a kick to his right ankle from Magpies’ wideman Yoan Gouffran, and the Republic of Ireland international was stretchered off.
Dyche said on Saturday: “He’s seen a specialist but he resees him on Monday (yesterday).
“He’s got a minor fracture in the bottom of his ankle.
“It’s pretty straightforward, obviously he can’t play but it’s pretty straightforward and it’s just a time issue now to get that well again.”
Ward, a summer signing from Wolves, made six successive starts after displacing Ben Mee.
Mee came on for Ward against Newcastle, and was a starter in the 2-0 defeat at QPR on Saturday.
