Burton have signed former Crewe and Port Vale goalkeeper Stuart Tomlinson on a four-month deal.
Tomlinson, 27, who was a free agent after leaving Vale at the end of last season, will challenge Ross Atkins for the number one jersey at the Pirelli Stadium.
Tomlinson's arrival means 21-year-old keeper Dean Lyness is likely to be sent out on loan.
"I just felt we needed a little bit more presence and size at this moment in time. He's a free agent, we've seen him before and he's been training here and he's a keeper I've always liked when we've played against him at Port Vale," said Burton boss Gary Rowett.
"He's big, strong and a real commanding presence. We felt as if he was a good body to get in and now we're getting into the season I feel he's the right type of keeper to add to what we already have.
"He will come in and add some real competition. I thought Dean did particularly well [at Coventry in midweek] but he's one we have earmarked for the future and I just feel perhaps at this moment in time this will give us the opportunity to get him out [on loan] and get him some regular games.
"Ross has done well and made some good saves, particularly at Sheffield United and Leicester. But sometimes it would be nice to have that presence at a set-piece to come and knock someone out of the way and catch it and add a bit more experience in there."
