Jimmy Calderwood has added another player to the first team squad with the signing of former Don Derek Young.

The 27 year old will be the fourth signing of the summer joining Jackie McNamara, Lee Mair and Jeffrey de Visscher and will meet his new team-mates on their return from Egypt on Monday.

Young, who originally signed for the Dons back in 1996, made 129 appearances between 1998 and 2003.
