Luton have made their ninth summer signing following the arrival of winger Danny Green.
Notts County have signed Togo international Mawouna Amevor on a two-year deal.
Queens Park Rangers manager Harry Redknapp has played down talk linking him with January moves for Joe Cole, Darren Bent and Frank Lampard.
Redknapp has been linked with all three players when the transfer window reopens as he looks to bolster his squad at Loftus Road.
Lampard's long-term future at Chelsea has been the subject of speculation in recent weeks with the England man out of contract in the summer.
Chelsea interim boss Rafa Benitez fuelled speculation on Lampard's future by recently suggesting the 34-year-old would be leaving Stamford Bridge.
Redknapp, who is Lampard's uncle, has dismissed talk of a possible bid to sign the midfielder in January.
"Yeah, Frank's really keen to leave Chelsea," joked Redknapp. "Frank's always wanted to play for QPR. He's not interested about playing Champions League or winning it again this year."
Cole and Bent have both previously played under Redknapp and their futures at Liverpool and Aston Villa respectively have been the subject of conjecture.
Redknapp is a confrimed admirer of the duo, but he has hinted QPR will not spend big in the transfer window if they do not appear to have a realistic chance of staying in the Premier League.
"Darren Bent's a good player. They paid 20-odd million for him but I'm not even looking at January," said Redknapp.
"I've always liked Joe. I signed him for West Ham at 11 years old so no-one knows more about him than me.
"I still think he's got talent and there's a top player there, but I've made no enquiry about Joe. I've had no contact with his agent or anyone."
Meanwhile Redknapp also refused to rule out a move for Marseille striker Loic Remy, but conceded any deal could prove expensive.
Redknapp has been a long-term admirer of Remy having tried to sign him when he was in charge of Tottenham and he admits their position in the league will decide whether or not they move for the Frenchman in January.
"I was interested in Remy at Tottenham but that was then. It's a different situation now. He would be expensive," admitted Redknapp.
"It all depends where we are in January depends how are we are going."
Redknapp added: "I'm not looking at January. It's about now. There are games between now and the window that will decide where we're going.
"If we don't pick up some points and wins in that period, what's the point of putting yourself in trouble trying to buy players?
"That way you could get lumbered with a big wage bill for next season. It's not the situation we want.
"We need to pick some points up. If we're in the mix then we can take a look at it again in January.
"I haven't discussed players with anyone - the chairman or chief executive.
"We need to win matches now. What happens in January is way off. I've not looked at targets for January."
Redknapp is convinced he can mastermind QPR's Premier League survival after rescuing Portsmouth from a similarly bleak position in the 2005-06 season.
"It's going to be tough but we'll give it our best shot, it's all we can do," he said.
"I'm optimistic, I think we can do it. I haven't come here to age myself another 10 years - if I didn't think we could do it I wouldn't be here.
"This is a good club that deserves to stay in the league. They made a bit of effort in the summer and now we must get the wins we need.
"It's a similar situation to Portsmouth. It was pretty desperate at that time but we managed to put a run together.
"You just need that one result to set you off and that came when we played Man City at home, scoring an injury-time goal.
"It was like we'd won the league we were so up. Then we went on a run and picked up an unbelievable amount of points that got us out of trouble.
"We need a win to get us up and running. We've got the players to do it, we've got some real good players."
