33-year-old Holden began his career at Bolton Wanderers, signing pro-terms in 1998, but after making just thirteen appearances in four-years he departed for Oldham Athletic in 2002, following a successful loan period.
Dean, who made over one hundred first-team appearances for Oldham, left the Latics for Peterborough United in 2005, after over fifty first-team appearances he was sold Falkirk in January 2007 for an undisclosed fee. Dean suffered a broken leg just over a year later whilst playing Celtic, this kept him out for ten months.
In June 2009 Dean signed for Shrewsbury Town where he went on to make over fifty first-team appearances and had a spell on loan with Rotherham United.
Dean's contract cancelled by mutual consent during the January 2011 Transfer Deadline Day.
Just a few days after his departure from the Shrews, Dean penned a short-term deal with Chesterfield before signing a one-year contract at the end of the season.
However in November he joined Rochdale on a short-term loan which was made permanent the following January.
Dean was released by Rochdale at the end of the season.
In July 2012, he penned a one-year contract with Walsall Football Club following a brief trial spell, he has made around twenty first-team appearances for The Saddlers and has become something of a fan favourite.
As part of his new deal Dean will join the Walsall coaching staff and is set to take up the role of Pro Development Coach, looking after the players in the 18-21 age group.
