| The McDiarmid Park match is live on BBC (8.05) with an away tie against the Forfar-Forres winners lying in store.
Craig has a hamstring injury and Milne a thigh knock.
Martin Hardie and Peter MacDonald look certain to be missing due to injury, but Kevin Moon, Collin Samuel and Derek Holmes have recovered from knocks.
And, with Hibs being out of the cup, Saints can field Paul Hanlon, on loan from the Easter Road outfit.
The last two cup-ties between the Perth outfit and Rangers have been close affairs.
Last season’s Scottish Cup semi saw Saints lose out on penalties after the sides were tied 1-1 after extra-time.
The previous season saw the McDiarmid Park men help expedite Paul Le Guen’s departure from the Ibrox managerial post after a 2-0 win at Ibrox in the CIS Cup.
However, all this has served as a warning to Rangers that St Johnstone will be difficult opponents at the start of an important fortnight for the Perth club.
Five points ahead at the top of the First Division, Saints face two of their promotion challengers in the next two weeks.
Partick at Firhill are first up on Saturday, followed by Dunfermline at McDiarmid Park the following Saturday.
The First Division title and a return to the SPL is Saints’ priority, but, right now, their focus is on facing Rangers tonight.
Boss Derek McInnes insists his men won’t be on a revenge mission tonight following last season’s semi-final exit.
“If the players want to use it as extra motivation, that’s fine,” said Derek. “But when the game kicks off, I don’t think there will be many thoughts about what happened before. There will be some different players involved on both sides, anyway.
“It’s not a question of revenge. It’s just about trying to do well as a team and hoping we can cause Rangers problems — as we did in that semi-final.”
Former Ibrox star McInnes believes his current team is even stronger than the one which ran Rangers close last term, but accepts Saints will still be widely regarded as underdogs.
“We are 14 games undefeated and I feel we are better equipped as a team than we were that day,” he said.
“Everyone who played in that game did exceptionally well and we ran Rangers very close. But Rangers went on to win the tournament, and that shows you their strength and doggedness. We are well aware of that and we know we have to play well.”
So far, Saints have sold 3500 of their ticket allocation. |
