Barrow have signed defender Haydn Hollis from League One side Notts County on an initial one-month deal.
The 18-year-old signed a one-year professional contract at the beginning of the season after a successful spell as a scholar at Meadow Lane.
"He comes with a good reputation and one for the future," joint-boss Dave Bayliss told BBC Radio Cumbria.
"At 6ft 4in he's got a physical presence, which is what we need at this level, and we're delighted."
Injuries to and Mike Pearson have depleted the Bluebirds' defensive options, with Adam Quinn the only recognised centre-back in the Barrow ranks.
"They see it as a really big part of his development, they've had a couple of offers from League Two teams to go on trial but he needs to play games," Bayliss continued.
"We've got seven big competitive matches in this league so it'll do the kid a world of good.
"We're thankful to Martin Allen and John Schofield at Notts County for giving us the opportunity."
