Fulham striker Adam Taggart is set to join Dundee United on loan from Fulham, who are looking to send Nikolay Bodurov out on loan.
Bulgarian defender Bodurov, 29, will slip down the pecking order following the arrival of Richard Stearman, who is having a medical ahead of a move from Wolves.
Australian Taggart, 22, has not made a first-team appearance for the Whites since being signed from Newcastle Jets last summer.
He is set to spend the rest of the season in Scotland after a deal was agreed with United.
Bodurov, meanwhile, also moved to Craven Cottage a year ago and has since made 41 league appearances.
Fulham manager Kit Symons has been keen to sign another centre-back in addition to Tim Ream, who was recently brought in from Bolton.
