Leeds have completed the signing of Neil Kilkenny from Birmingham but the League One promotion chasers will not be signing Luton's Dean Morgan.
Morgan's move to Leeds is off
Leeds had a bid for Morgan accepted by Luton's administrators but failed to agree personal terms with the striker.
Morgan, who has been on loan at Southend since November, had expected to complete his Leeds move on Monday.
Midfielder Kilkenny, 22, has signed a three-and-a-half-year deal at Elland Road having initially joined on loan.
