MILLWALL ARE hoping to sign Simeon Jackson before Friday's transfer deadline.
Jackson, who is also on the radar of south London rivals Charlton, has held talks with boss Ian Holloway about a move to The Den.
The 26-year-old was a summer target for the Lions but moved to German outfit Eintracht Braunschweig instead.
But Jackson has struggled in the Bundesliga, failing to score in nine appearances so far this season, and now he wants out.
The former Norwich frontman has asked to cancel his contract and his agents are currently negotiating a pay-off.
Holloway is also in the market for a right-sided centre back, but he may wait until the loan window reopens in a week's time to strengthen his defence.
If Jackson is to return to English football, with London his preferred destination, he must reach an agreement with Braunschweig by 11pm tomorrow night.
Provided the striker is a free agent by then, Millwall – or any other club – will be able to sign him outside of the transfer window.
But Jackson's exit from Germany will depend on him having a deal lined up elsewhere, so the likelihood is that he will be on the move in the next 48 hours.
A source confirmed: "It is likely that Jackson will come back to the UK and his club are doing a deal with him.
"But as every club would do, they are waiting to see who wants to take him before they finalise a pay-off with him.
"He needs to be paid up by Friday, but after that he is a free agent and would be available to sign any time.
"Millwall are very interested but a lot of things have got to happen very quickly for the deal to go through."
One player who could be leaving SE16 this week is Scott McDonald.
McDonald was left out of the Lions squad for the 1-1 draw with Sheffield Wednesday and it is understood he has held amicable discussions will Holloway about a move elsewhere.
The Australian's agents are said to be exploring possible destinations for the 30-year-old – be that on loan or a permanent basis – ahead of Friday's deadline.
Meanwhile, Holloway has fired a warning to the out-of-contract players in his squad, telling them that they must decide quickly whether or not to sign new deals.
Contract talks were held with Liam Trotter and David Forde before Christmas, whilst several other players have been promised fresh terms.
"I made some decisions [for the Wednesday game] and I believe they were the right ones given the response I got out of the group," Holloway said.
"Now what is going to happen is this: if you don't sign your contract, I might have to get rid of you because I talk about commitment.
"I want to be here and I want people to want to be with me, and if they don't I have got to be a businessman and sort it out.
"We've got two days left of the window, but there is also the loan window after that and it makes life a lot easier. I'll be making some decisions.
"I am not a miracle worker but I develop groups of people who want to work hard for each other and trust each other. Normally they out-play their wages by a zillion miles, so that's what I've got to do here.
"It's not about how much you might want next year, or what you might get from somebody else, I don't deal that way. 'Do you want to play for me son?'
"They've seen me now, so they should turn around and say 'yes please' or 'not really, I'm going.' If that's what they want, we will move them on and see where we are."
Meanwhile, young Millwall striker Aiden O'Brien has joined League Two side Torquay United on an initial one-month loan.
