Table-topping Morton will be missing full-back Willie Dyer through suspension when they host promotion dark horses Livingston at Cappielow.
Also absent for the Greenock side will be pelvic injury-victim Archie Campbell and Steven Stirling, who broke a leg earlier this season.
Manager Allan Moore will utilise either Craig Reid or Jordan Halsman to cover for Dyer.
He said: ``Jordan would come in as a replacement whereas moving Craig over could mean other changes so I have not finalised my selection.
``The game plan will be to stop Livingston getting into a rhythm and passing the ball all around us.
``If we do that we can get the win that opens up a 15 point gap on them which could prove crucial.''
Livingston will travel without defender Paul Watson.
Watson made his comeback from four months out with a knee injury in a midweek reserve game but will not be included as he needs more game time.
Also missing for the Lions are Jason Talbot and Keaghan Jacobs, who have had knee surgery, and Ross Docherty with a groin injury.
Head coach Gareth Evans said: ``Morton are a big, strong and experienced team who deserve to be where they are.
``They will be looking to build on their win at Falkirk last week that took them back to the top so we need to play to the highest standard we can.''
