Burnley have been placed under a transfer embargo by the English Football League - just three months before the window re-opens.
The Championship club confirmed the news on Sunday evening. Burnley claim the "immediate" embargo was introduced after the late submission of their financial accounts to the EFL but insist they are "confident" the situation will be resolved "swiftly".
Burnley are managed by Manchester City legend Vincent Kompany. The Clarets are on course to win the Championship title and return to the Premier League at the first attempt, as they sit 13 points clear of Sheffield United in second with just 10 games left.
