He said: "Due to a couple of knocks in a (reserve) game on Monday we only had eight training on Tuesday, slightly better today, we were up to 12.

"There are still two or three that are going be right to the last minutes and we won't get a decision until on them until Saturday.

"We know that we are going to be without Iain Wilson who is going to be cup-tied after playing for Kilmarnock in the previous round.

"So we will give all our injured players up until the last minute to try to prove their fitness for a big game on Sunday.

"Obviously they all want to play, these games don't come around too often and you want to make sure that if you miss it, there is a real good reason why you are missing it.

"We haven't really filled the bench all season, we have generally played with 15 or 16 all season, I am quite comfortable with that.

"As long as I have a substitute goalkeeper and three outfield subs, I am quite happy to go with 15 players. You can only bring three on.

"It might be another two weeks that we get the 18-man squad fully available."
