Burton have signed young goalkeeper James Wren on a one-year contract.
The 18-year-old former Walsall youth-team player has been training with the Brewers since the start of the season.
Wren told the club's website: "There's good people who I can work with. The likes of Kev Poole and the gaffer, who is especially good with young lads.
"I feel like I have come on straight away since I have been here, especially working with someone as experienced as Kevin giving me little tips."
