Burnley manager Brian Laws is waiting to hear from Portsmouth after deciding to extend David Nugent's loan stay at Turf Moor until the end of the season.
Pompey now have to decide whether to honour their agreement, or sell the striker to another club.
Laws said: "There's an agreement in place that's been there for a long time with Portsmouth. We're waiting for Portsmouth's reply and the paperwork going ahead. We've got to the point where we've done our bit, now we're expecting Portsmouth to do their bit.
"I'm hoping the paperwork will come through in time for the weekend. The paperwork is complicated, but we're exercising the right, and therefore we're expecting Portsmouth to honour their part of the bargain."
Meanwhile, Laws has admitted that he is interested in signing Celtic's Danny Fox but the left-back is not his only target.
The 23-year-old moved to Glasgow from Coventry City last summer and has made 24 appearances for the Bhoys so far this term.
However, he is believed to be keen to return to England, with Laws saying: "He's one of quite a few players that I'm talking to and one thing very evident is that they all want to come here and that's very, very pleasing.
"He's one of many options, and if it's not Fox it will be someone else. No deal has been done yet and we've done a lot of talking with a lot of people.
"We can't say one player is the first choice because he might not want to come or we can't do the deal, so you've got to have options A, B and C.
"I'm trying to sign a few more players. I'm hoping to conclude at least a couple more players before the window shuts."
