Morton hope defender Kevin McKinlay and midfielder Fred Bachirou shake off knocks but Kevin Kelbie and Sean Fitzharris have both been ruled out.Dundee welcome back defensive players Craig McKeown, Gary Irvine and Rhys Weston from suspension for the First Division trip to Cappielow.
Striker Sean Higgins remains out injured for the Dens Par side.
Eight points separate fourth-placed Morton and seventh-placed Dundee with four games to play.
Morton manager Allan Moore: "I want Morton to establish themselves very much a top half of the table team and the best way to do that is by winning all our games between now and the end of the season.
"We have not had much luck against Dundee this season and hopefully if we get a wee break in this game we will come out on top."
Dundee manager Barry Smith: "We have almost everyone we can have available to us and we will go all out to get the three points we need.
"There has not been a lot between the sides so far this season and a repeat of the 1-0 win we got down there the last time would be ideal.
"It has been five games since we won and I am sure everyone at Dundee would be delighted to bring that run to an end."
