Scottish Cup finalists Ross County welcome back midfielder Steven Watt for the trip to Cappielow and have no injury or suspension problems.
County surprised Celtic with a 2-0 win in the Cup on Sunday.
Morton manager James Grady: "We have a few players with bumps and bruises.
"And it looks like the extra couple of days at the weekend due to County's Cup game has worked in our favour as I am hopeful the injured players will be available."
Ross County manager Derek Adams: "I had always said before the Cup run that progress this season would be judged on beating our points total and then finishing higher in the table.
"It has been a hectic few days, but everyone was buoyant at training on Monday. We will have our feet on the ground by the time we kick off at Greenock."
