Doncaster have made forward Dany N'Guessan their sixth summer signing.
Tottenham have confirmed that Romanian defender Vlad Chiriches has completed a move to Napoli.
QPR chairman Tony Fernandes issued another vote of confidence to Mark Hughes on Monday after the club's miserable start to the season continued.
Rangers went into the international break rooted to the foot of the Barclays Premier League, having crashed to defeat at West Brom on Saturday.
They have taken just two points from their opening seven games and have also been knocked out of the Capital One Cup, leading to calls from some fans for manager Hughes to be sacked and replaced with former Tottenham manager Harry Redknapp.
But Fernandes told talkSPORT on Monday morning: "Of course, we need a couple of results. But we have to be real.
"You could be Sir Matt Busby, Sir Alex Ferguson, or whoever the greatest manager is.
"But when you're suddenly playing with four centre-backs and you haven't had the stability of a defence - every game he's had to change, put people out of position - we're going to struggle a bit."
Fernandes, who helped bankroll the signing of 12 new players this summer, added: "I was looking at the table today.
"Nobody is panicking here, certainly not myself. We've been a bit unlucky.
"It takes time for people to gel together. There were different levels of fitnesses and, unfortunately, we were beset with injuries.
"But if you look at how we've played - bar the Swansea game - there hasn't been a team that really outplayed us.
"We just have to be patient, I have full faith in Mark and the team and the coaching staff."
Fernandes became majority shareholder just over a year ago at QPR, who sacked manager Neil Warnock in January.
"We've only been around for one year," he said.
"Rome can't be built in a day and I'm not a short-term person, and we need stability more than anything."
Asked about the increasing demand for the club to send an SOS to former Tottenham boss Redknapp, Fernandes said: "Many people have told me that I should lead the board.
"When you go down to Loftus Road, fans there are very reasonable and they understand what we're trying to build and I don't think anyone wants an unstable situation.
"So I think the fans are behind what we're doing.
"But we can't make everyone happy - that's life.
"We're on a mission, we're on a vision and we have to keep to that project and keep calm and have faith that what we're doing will all turn right."
