Barrow have signed defender Angus MacDonald on a short-term contract until the end of the season.
MacDonald has been without a club since leaving League One Exeter City at the end of the season.
The 33-year-old has played over 350 games in his career including for three clubs in the Championship and Aberdeen in the Scottish Premiership.
“I’ve known Angus for a long-time, he’s a top defender and a strong leader,” Barrow head coach Dino Maamria told the club’s website, external.
“Although he has been a free agent, he’s kept himself in good shape and has trained with Exeter City, so, he’s ready.
“It’s not always ideal signing outside the window, but his quality, experience and presence will give us what we need right now.”
Barrow slipped into League Two’s relegation zone on Tuesday night following Newport County’s win over Tranmere Rovers.
But the Bluebirds have two games in hand over Newport and Crawley Town and will climb above both if they avoid defeat at Cheltenham Town on Friday (19:45 GMT).
