Rangers v Celtic
Leaders Celtic travel to arch-rivals Rangers for a midday kick-off on Sunday.
The Hoops will be protecting a current six-point advantage over their hosts while also having a game in hand.
They are boosted by centre-back Dedryck Boyata and midfielder Stuart Armstrong both returning from injury, although right-back Mikael Lustig is suspended.
Otherwise, Nir Bitton, Craig Gordon, Leigh Griffiths and Jonny Hayes remain sidelined.
"We've managed to get Stuart Armstrong back, which is great news for us," manager Brendan Rodgers confirmed to BBC Scotland. "Dedryck [Boyata] is back, been training really well, so he's available.
"Leigh [Griffiths] is out training but this game's come a bit too soon for him, so hopefully he won't be too long."
Rangers must check on defender Russell Martin and winger Jamie Murphy, while skipper Lee Wallace and Declan John are both nearing returns.
However, the hosts are still missing Graham Dorrans, Ryan Jack, Ross McCrorie and Jordan Rossiter.
