Morton striker Peter Weatherson is a doubt with a back problem with the match facing an 0830 GMT inspection.On-loan Celtic youngster Sean Fitzharris is included in manager Allan Moore's plans for the last time before returning to Parkhead.

Dundee's interim manager Barry Smith will look to make it six games in a row without defeat under his stewardship.

Smith has injury concerns over one unnamed player but no clues were being given out to his identity.

Morton manager Allan Moore: "(Groundsman) Mark (Farrell) has put a huge effort in to make the pitch playable and apart from a very slight layering of frost it is like a bowling green.

"It would be good if the boys go out and earn him the three points as a reward."

Dundee manager Barry Smith: "Morton will be well organised and full of energy and we have to match that."
