Kilmarnock v Celtic (15:00 GMT)
Kilmarnock faces a setback as key defender Stuart Findlay is out for several months following an ankle injury at Dundee. Midfielder Liam Polworth could return to bolster the squad, while Kyle Magennis continues his recovery.

Celtic, meanwhile, sees slight concerns with American centre-backs Cameron Carter-Vickers and Auston Trusty, who both missed Friday’s training but may still feature. Odin Thiago Holm, however, remains sidelined with ongoing calf issues.

Rangers v Hearts (17:00 GMT)
Rangers welcome Ianis Hagi and Danilo back into the squad, as they weren’t included in the recent European lineup. Ridvan Yilmaz and Rabbi Matondo may also make appearances, though Oscar Cortes isn’t quite ready. Tom Lawrence, unfortunately, is out for up to six weeks due to a leg injury.

Hearts head coach Neil Critchley has no new fitness concerns and is likely to pick an unchanged side. Yutaro Oda and Calem Nieuwenhof are nearing a return but aren’t expected to feature at Ibrox.
