Cardiff have signed Jason Koumas on a season-long loan from Wigan.
The midfielder will not however be able to make his debut until the club's transfer embargo is lifted.
The cash-strapped npower Championship outfit have been under embargo for most of the summer but are working to lift the ban by the start of the new season this weekend.
Koumas joins fellow summer signings Tom Heaton and Daniel Drinkwater in currently being unable to feature in Sunday's opener at home to Sheffield United.
The Wrexham-born 30-year-old enjoyed a successful year-long spell in the Welsh capital while on loan from West Brom in 2005/06, before sealing a permanent move from the Hawthorns to Wigan, where he has struggled to find top form.
Bluebirds chief executive Gethin Jenkins told City's official website, www.cardiffcityfc.co.uk: "We continue to work towards removing hurdles at the club and are working with the intention to come out of embargo ahead of the new season.
"During this time, Dave [Jones, manager] has presented targets including Jason Koumas as he looks to strengthen the squad.
"We are pleased to have agreed terms with Wigan and to welcome Jason back to Cardiff City."
