Motherwell have cut admission prices to just £5 in a bid to boost the attendance against St Mirren on Saturday. The Lanarkshire side must beat St Mirren to stand a chance of securing a top-six place.
A home win would leave Hibernian needing victory over Rangers on Sunday to pip Motherwell to the remaining top-six spot.
Chairman John Boyle said: "We want to fill Fir Park to the rafters and create a cup-tie atmosphere to get right behind our team.
"At a fiver a head, we hope that we can lift a little of the doom and despondency that is so prevalent today by creating a party atmosphere at Fir Park this Saturday."
Boyle also announced the club would end the unpopular practice of moving season-ticket holders from their seats in the Davie Cooper Stand to accommodate Old Firm fans.
He added: "Listening to our fans is going to be at the heart of everything we do now and in the future, and we hope we have got off to a good start."
