The Norwich City striker has been heavily linked with an Elland Road switch.
The news comes from Italian journalist Emanuele Giulianelli. He has recently reported on such transfers as the arrival of Sol Bamba and Mirco Antenucci to Leeds United and seems to be partially in the know about events at Elland Road.
He claims that Lafferty will sign a six-month loan deal with the option of making it a permanent two-year deal in the summer if the Northern Irishman proves a success.
The report claims that the move was agreed on the 30th December and he will be announced next week.
The move will not come as a shock if it does prove to be done.
Lafferty has long been on the radar at Leeds with manager Steve Evans and chairman Massimo Cellino both big fans of the Northern Ireland international.
He has not been able to buy a game at Norwich this season but impressed with his displays for his country - scoring seven goals in nine games as Northern Ireland qualified for the finals in France next year.
Hopefully Leeds will get their man and he can manage to produce some of that form at Elland Road.
