O'Ware fit for Morton
Defender Thomas O'Ware could make a first appearance of the season following a foot injury when bottom-of-the-table Morton host Dumbarton.
Craig Reid and Marc Fitzpatrick are expected to shake off knocks to feature, however Michal Habai is a major doubt with an ankle injury and David O'Brien (shoulder) and Reece Hands (pelvis) remain out.
Manager Allan Moore said: "Our last game was against St Johnstone in the Scottish League Cup and even though we lost we showed what we are capable of.
"If we play like we did that night and get a goal ahead I am sure we will go on and get the win we need."
Dumbarton, who defeated the Greenock side 3-1 earlier in the season, welcome back Chris Turner from suspension but ankle injuries rule out Garry Fleming and Scott Smith.
Sons boss Ian Murray said: "Morton may well be having a difficult run, but playing at Cappielow is never easy.
"We won there at the start of this year. That win brought our season alive and they are probably looking for this fixture to do that for them.
"We are going there after a good win in the cup over Cowdenbeath and on the back of three good away wins in a row, so we can be confident of earning something."
