It’s the first meeting of the two teams this season, with a place in next month’s semi-finals the prize.
From the midweek victory over St Mirren, there’s just the one change as Minsu comes in to replace Badredine Bouanani.
That means Rangers start with Ivor Pandur in goal behind a back four of Dujon Sterling, Emmanuel Fernandez, Olwethu Makhanya and James Penrice.
Dan Neil and Nico Raskin are once again in midfield, with Minsu and Djeidi Gassama providing the support for strikers Kevin Kelsy and Ryan Naderi.
On the bench this afternoon are Liam Kelly, Ross McCrorie, Ben Godfrey, Vanja Dragojevic, Cammy Devlin, Tochi Chukwuani, Findlay Curtis, Badredine Bouanani and Bojan Miovski.
Kick-off at Ibrox is 12pm, and supporters outside of the UK can watch the match live on RangersTV.
RANGERS: Pandur, Sterling, Fernandez, Makhanya, Penrice, Neil, Raskin, Minsu, Gassama, Kelsy, Naderi.
Subs: Kelly, McCrorie, Godfrey, Dragojevic, Devlin, Chukwuani, Curtis, Bouanani, Miovski
