Thistle boss Stuart Davidson is calling on his players to all stand up and be counted as they look to get a result against league champions Beith.
It is a 2pm kick-off on Saturday at Bellsdale Park as Largs lick their wounds following a shock defeat to Lesmahagow and look to bounce back.
Davidson has said he holds no fears going into the big Beith clash and believes his side have what it takes to upset 'The Mighty' on their home turf.
The good news for Largs is that defender Nicky Jamieson should be back in the reckoning after sustaining a head knock, but striker John Carter is out for the next few weeks after an ankle injury.
Keeper Sean Graham is also back fit after a recent lay-off while other goalie Blair Cousar is still recovering from his latest injury setback.
Davidson said: "I thought we started alright and we were creating chances, but we didn't get the early goal.
"Lesmahagow got the penalty but it was still early in the game and there was plenty of time for us to react.
"We had some good chances including the penalty but we didn't take them.
"We kept at it and we sensed the goal was coming and then when we did equalise it looked like we were going to go on and win it, but then we gave away a cheap goal.
"We didn't take control of the situation.
"I am not blaming the defence - it is a team game and we must stick together.
"Everyone including myself is responsible for what happened and we need to look at ourselves from missed chances to giving away goals and look to improve.
"We had a few bursts into the Lesmahagow box but it didn't happen for us.
"The bottom line is that it just wasn't good enough.
"Lesmahagow did what they had to do and full credit to them.
"I know a lot has been made of the park but we can't look at that as a reason.
"These kind of pitches are not alien to us as we have all played football on them before and know what it is all about.
"I changed the shape on Saturday to make us a bit more direct.
"We have some possible heavy parks coming up at Beith and Darvel and we really need to adapt and be ready for it. 
"We can't use the pitch as an excuse for a poor result; we all have to stand up and be counted."
"Every player in our squad is capable of playing well in the Premier and we should have been good enough to beat Lesmahagow, but we didn't.
"It is all about how we react now."
And the Thistle boss believes Beith will be at full throttle with their big William Hill Scottish Cup match a week later at home to Ayr United.
"I don't think they will be taking their eye off the ball," said Davidson, "In fact I think it will be the opposite as their players will be wanting to impress their manager to get into the team.
"We all know about Beith's qualities, and on Saturday this is where we are looking for a reaction.
"We have just had our poorest result of the season and we want to go and put on a good display and then go to Darvel a week later and get into the next round of the Scottish Cup.
"We are approaching these games with something to prove.
"We know that going forward we can hurt any team in the league and I am really looking forward to seeing how we react, and I feel we really can step up to the mark and get a good result at Beith."
"We beat Beith in the West of Scotland Cup on penalties a few season back, and we have had a number of close games.
"We have a better squad and better quality of player now, and we have to make sure we turn up on the day and show what we are capable of."
