Striker Francisco Sandaza returns from a three-game ban for the last SPL game of the season.
Midfielder Lee Croft remains out with a hamstring injury.

Dorin Goian picked up a knee injury last weekend and has been granted leave to return to Romania, while United States skipper Carlos Bocanegra has also returned to his homeland ahead of their international games this summer.

However, the Northern Irishman said: "No matter what team Rangers put out we will still be the underdogs
"I watched them destroy Dundee United recently and they had chances to win in the draw against Motherwell last week.
"But I don't want to focus on Rangers, I want to focus on ourselves. I am looking for one more push for Europe over 90 minutes, we have a few players leaving and they will want to leave on a high."
