Ross County manager Jim McIntyre has made Hartlepool United defender Darren Holden his fifth signing of the summer.
The 21-year-old has agreed a two-year deal at the Global Energy Stadium as McIntyre continues to build for the 2015/16 campaign.
Brian Graham (Dundee United), Ian McShane (Queen of the South), Michael Gardyne (Dundee United) and Scott Fox (Partick Thistle) have already moved to Dingwall during the close season.
