Midfielder Didier Digard has extended his contract with Nice, the club have annouced ahead of the new Ligue 1 season.
The 27-year-old joined the Ligue 1 side in 2011 after loan spells at the Stade Municipal du Ray from Middlesbrough and has now committed his future to the club with a new deal, the length of which has not been specified.
A statement on the club's official website said: "The president of the Eaglets, Jean-Pierre Rivere, announced good news at the team presentation at the Villa Massena.
"The Nice captain Didier Digard has extended his adventure with the Red and Black."
Investment banker Dalman takes over from Simon Lim, who had been acting chairman following Dato Chan Tien Ghee's decision to step down in March.
Lim will continue as the Bluebirds' chief executive.
Cypriot Dalman, who has previously worked with Deutsche Bank and Credit Suisse, told the club's official website: "I am honoured to take up the role of club chairman at Cardiff City Football Club.
"I have enjoyed my time at the club since joining the board of directors in January 2012 and now relish the opportunity to contribute further in my additional role as chairman with Cardiff City in the Barclays Premier League."
Club owner Vincent Tan, who last week reached agreement with finance company Langston over the club's long-standing debt, added: "I am delighted to welcome Mehmet Dalman into his new and additional role at Cardiff City Football Club and look forward to many successful years ahead.
"Mehmet has had many years of experience in business across the world which he has brought to this great club since becoming a non-executive director in January last year.
"This is more great news for the football club following last week's amicable resolution with the Langston Corporation in which Mehmet played a big role. I wish him the best of luck in his additional role at Cardiff City."
Owain Fon Williams is currently sidelined with injury and the speed of his recovery is likely to determine Moore's decision.
The Rovers boss has not ruled Fon Williams out of contention for Saturday's meeting with Walsall and is expected to make a decision on Tuesday.
"He's improving. I spoke to him on Sunday and it has certainly got better," Moore told the club's official website.
"We have got the opportunity to bring someone in, we've got someone lined up to do that. But I'm not going to bring him in if Fonners is going to be okay.
"We'll wait and see and I'll know more on Tuesday."
