Vernon has signed a new deal that will keep him at the club until the summer of 2014.
Considine’s new contract will keep him with the Scottish side until the summer of 2015.
Manager Craig Brown told the club’s official website. “Both Scott and Andy are integral to my plans here at the club and I’m naturally very pleased they have pledged their futures here.
“I have already gone on record that I believe Scott can reach the 20-goal tally this season while Andy is the most improved player in our squad this season and one of the first names on the team-sheet each week.”
