Ards have landed Linfield defender David Armstrong just three days before their return to the Danske Bank Premiership, after a seven year absence.
Ards moved quickly to secure the signature of Armstrong after the Blues released him on Tuesday afternoon.
Ards manager Niall Currie said: "We are delighted to welcome someone of David Armstrong's calibre to our club.
"Armstrong is a quality defender who has won medals at Windsor Park and played across the water as a professional.
"At the age of 26 he has both experience and a big future in front of him.
"I was already very happy with the squad we had put together, but when a player like Armstrong becomes available, you don't want to miss out."
Speaking at the launch of the new NIFL Danske Bank season Currie said: "When I was a player Ards were always Premiership club, so it's only right that we are back up there again.
"We worked hard to reach this level and it is now our job to keep the club there.
"Ards have been through some tough times in recent years, so we want to stabilise them in the top division. It's a massive challenge, but it's one we're excited about."
David will follow in the footsteps of his father Winkie Armstrong, who played for Ards in the 1980s. He started his career at Lisburn Youth, before moving to Hearts. During his six year stint at Tynecastle he enjoyed loan spells at Cowdenbeath, Raith Rovers and Crusaders, before signing for Linfield in 2010.
Linfield boss David Jeffrey said: "As with Ryan Henderson, an agreement has been reached between the club and David Armstrong for David's contract to be cancelled by mutual consent.
"I want to take this opportunity to thank David for his efforts and contribution since he joined the club from Hearts."
Ards also hope to sign Glentoran midfielder Steven Gordon, 20, on a season long loan tonight.
Gordon played for Ards Reserves in their 4-2 victory over Dromara Village, on Tuesday night.
The Newtownards native made ten league appearances for Glentoran last season before making his European début against Icelandic side KR last month.
On Christmas morning he played a key role in Glentoran Seconds' 3-0 win over Ards in the Steel & Sons Cup final, before finishing the season on loan at Lisburn Distillery.
