Crawley defender Kyle McFadzean will complete a move to League One rivals MK Dons this morning.

The details of the transfer have yet to be confirmed but MK Dons let the transfer slip by posting a video of McFadzean on their website yesterday before hastily taking it down.

It means McFadzean will be reunited with former Crawley boss Richie Barker who is assistant manager at Stadium:mk.

The departure of the highly-rated 27-year-old – who was in the final year of his contract at Crawley - is no surprise after he turned down a move to Peterborough in January to finish the season at the Stadium.

Boss John Gregory had already moved to replace McFadzean by signing Sonny Bradley from Portsmouth for a small fee on Wednesday to take the number of central defenders at the club to four along with Connor Essam and Joe Walsh.

However, the fact McFadzean has joined another team in League One is slightly surprising after Gregory insisted the former Sheffield United trainee was good enough to play in the Championship or higher.

Gregory also claimed the former England non-league international was worth £1million but it is highly unlikely MK Dons have paid even half that amount.

Crawley will have to pay a proportion of any fee received from MK Dons to McFadzean’s former club Alfreton Town due to a sell-on clause inserted when he signed for Reds in August 2010.

McFadzean was the longest serving member of the Crawley squad having made 155 appearances over the last four years, scoring ten goals. It means Josh Simpson is the only survivor from the side which won the Conference title in 2011.
