Championship leaders Derby County have drafted striker Jon Macken in on a free transfer from Crystal Palace. Macken, 29, came through the Manchester United ranks but failed to break into the first-team and moved on to Preston.
He had a big impact at Deepdale and earned a �5m switch to Manchester City in February 2002.
Injury saw his progress limited at City and Macken joined Palace in July 2005 and he again struggled at Selhurst Park before being signed by Derby.
