McCluskey worry for Partick
Morton striker Jamie McCluskey is a doubt for the visit of Partick in the Scottish League Cup after sustaining a knock in Saturday's last-gasp 2-1 win at Peterhead.
Andrew Barrowman remains sidelined with a groin injury with manager Jim Duffy delighted to be facing the Jags after his side's injury-time winner at the weekend.
Duffy said: "That goal means we are going into this with a bit more confidence. We will need that as in the games I have seen Partick in this season they have been very good.
"They lost to a late goal on Saturday and will be looking to make up for that in this one."
Meanwhile, Conrad Balatoni is looking for Partick to come out fighting against Morton after their Hamilton horror show on Saturday.
The Maryhill men were not at their best in their Premiership clash against Accies but looked to have grabbed all three points when Kallum Higginbotham scored with a wonderful drive with five minutes remaining.
However, just two minutes later, Hamilton substitute Tony Andreu levelled from 12 yards as the Jags defence switched off before another Accies substitute, Jason Scotland, stunned the home side when he grabbed an injury-time winner.
Thistle get the chance to make amends for the defeat which saw them slip to eighth place in the table when they travel to Greenock for their second-round tie against a Morton side who have moved into second place in League One.
Balatoni, 23, insists Alan Archibald's men are ready to grab that opportunity with both hands.
"We've just got to put Saturday's performance behind us and focus on putting in a performance tomorrow and, most importantly, getting the win for the fans," the Englishman told Thistle's official website.
"The best way to bounce back from a result and performance like that is to come out fighting and get a good win under your belt - that's exactly what we're looking for.
"The good thing about football is there's always a game to go and rectify your mistakes when something has gone wrong.
"But if we're not at our best it's the sort of match where we could come undone.
"We know that Morton will be up for it and we just need to make sure we give them the respect they deserve and go out there to do a professional job.
"We know what to expect, they're still a strong team and they've got confidence on their side just now.
"They're probably going to be pushing for the league this year, along with a few others, so we need to take them seriously.
"It would be great for everybody around the club if we can progress and get further than we have done recently. All that starts on Tuesday night."
