With the transfer window slamming shutting at 5pm, it looked as though Danny Welbeck was going to be Preston's only signing during the January window.
However, in the last couple of minutes, a statement has been released confirming that Treacy, who will take up the number 16 shirt vacated my ex-skipper Paul McKenna, has signed a two-and-a-half year deal with an option of a third year.
The winger, who can play in either flank, has been on loan at Sheffield United earlier in the season where he made 17 appearances, scoring 1 goal.
