And there's even more Scottish Cup quarter-finals to bring you this weekend.
We're also into the last eight of the women's competition, with another Hibs v Rangers tie catching the eye.
What do you need to know? My colleague Charlotte Cohen has it covered.

What else to look out for this weekend?
There's a wee extra buzz around any Scottish Cup card.
Plenty to get stuck into this weekend, as Celtic host Livingston, Rangers travel to Hibs, and Greenock Morton fly the flag for the lower leagues as they take on Hearts. I'm absolutely buzzing about the atmosphere at Cappielow btw.
Here's a handy guide to what this quarter-final line-up could offer.

How'd they get here?
Aberdeen v Kilmarnock (12:15)

You might say the luck of the draw has been with Aberdeen in the Scottish Cup up to this point, with both of their opponents coming from League 2.
Clyde and Bonnyrigg Rose were both saw off with a 2-0 scoreline, but another clean sheet may be hard to come by this afternoon.
Kilmarnock had a tricky fourth round tie to navigate with Dundee, but a quick start was enough to seal progression.
League 1 Cove Rangers travelled to Rugby Park next, with a fairly routine win landing a spot in the last eight.

Kennedy missing for Kilmarnock
Aberdeen v Kilmarnock (12:15)
Derek McInnes hasn't been one to tinker unnecessarily this term, and makes just one switch from the side that grabbed a late point at Dens Park last time out.
It seems to be an enforced one with former Don Matty Kennedy missing from the squad entirely. He's replaced by David Watson, who scored an injury-time stunner when these sides last met at Pittodrie.
Lewis Mayo's suspension from the red card he was shown at Dundee won't kick in until Killie return to league action.

McGrath and MacKenzie return
Aberdeen v Kilmarnock (12:15)
Those Aberdeen players may still be reeling from their last outing at St Mirren last time out when two injury-time goals turned defeat into victory in the blink of an eye.
Neil Warnock makes two changes to that side, with Jack MacKenzie in for Richard Jensen at the back, while Jamie McGrath returns in place of Duk.
