Morton missing duo for Dumbarton test
Morton host Dumbarton without Conor Pepper and Mark Russell.
Pepper has a knee problem while Russell is suffering with a virus.
Ahead of the game Morton manager Jim Duffy said: "We played well against Falkirk last weekend but the win was taken away from us with a goal in injury time. We have had to take that on the chin and move on to facing a Dumbarton side that will be boosted by beating Dundee United.
"They have experienced players and we will be giving them full respect. However, if we play like we did last weekend I am sure that we will do okay."
Frazer Wright (ankle) and Garry Fleming (hamstring) are absent for Dumbarton but Darren Barr could return after a back complaint.
Sons boss Stephen Aitken said: "The boys trained hard during the opening weeks of the season when results were not great but there has been an extra spring in their step this week. However, we cannot rest on our laurels and think other results will come.
"Morton probably do not have as many points as they feel they deserve and will be out to make amends for that against us."
