Manager Colin Calderwood has a huge first-team squad at his disposal following the return from loan spells of the likes of Neil Harris and with strikers David Johnson and Scott Dobie returning to full fitness.
He said: "There is no way we can keep 33 people in the club.
"We don't have the facility even to play them in the reserves.
"There is no one cut and dried in the team.
"We've got enough competition in every position.
"The ones that handle the pressure of being competitive in training and the pressure of being the favourites in our league are the ones we want."
