Bury have announced that they have been placed under a transfer embargo by the Football League.
The struggling Shakers are currently prevented from making any new signings pending an investigation into a short-term loan they received from the Professional Footballers' Association.
A short statement on the League One club's website read: "Bury Football Club can confirm that they are currently under a Football League embargo for registering new players.
"This embargo is a result of the club obtaining a temporary short term loan from the PFA until mid January 2013.
"The club will make a further statement shortly."
Bury suffered a 2-0 defeat at home to Leyton Orient on Saturday which left them third from bottom in the division.
