“The damage was on the surface of the knee and the surgeon who operated on Steven in London has tidied things up and that should sort the problem,” said Saints’ team boss Owen Coyle.

Peter MacDonald is likely to continue up front in Steven’s absence and there are also places in the squad for teenage forwards Steven Doris and Andy Jackson.

Goran Stanic, who sustained a leg knock against Livingston, is OK and Martin Hardie and Jason Scotland, who were doubtful due to injury for the Livingston game but played, have suffered no reaction and will be in their usual places.

Kevin James, who has been out injured for several weeks, has resumed light training.

“This is another tough game and, as Ayr are underdogs, they have nothing to lose,” Owen added.

“Somerset Park is a ground I have personally done well at, so here’s hoping that continues tonight.”

The winners are away to Falkirk and, should Saints get through, Owen, plus Kevin James and Andy Lawrie, will be pitted against a club they gave great service to.

But Saints’ eyes are only on tonight’s game against The Honest Men.
