Adams unavailable. Geggan available with rest of squad. Rotation in midfield expected. No further injury or suspension news.
In testing wet conditions at Somerset Park Ayr drew 1-1 with Queen of the South last time out. Michael Rose put Ayr in front but Queens hit back with a late goal. Despite dropping points Ayr have opened up a four-point gap as Ross County were defeated by Dundee United.
Ayr smashed Morton 5-1 at Cappielow in their first meeting this season. Lawrence Shankland put them in front before Morton equalised. However, the closing quarter of the game was dominated by Ayr with Shankland scoring another, Craig Moore grabbing a double and Declan McDaid completing the scoring.
Ayr's form at Somerset had been perfect until the Queens encounter. The weather played a significant part in Ayr's failure to win and suggests they could struggle in heavy winter conditions. However, Ayr have only dropped two points at home from a possible 18 so far this season.
Jamie Adams (thigh) remains unavailable and is expected to remain out for around two weeks. Andy Geggan has recovered from illness and should be available to face Morton.
Ayr are managing their playing resources with care. There could be further squad rotation with Michael Moffat and Declan McDaid in contention for starts.
Veteran defender and club captain, Chris Higgins, returned to the bench last week. The popular defender has been out of action for almost a year but is finally fully fit and again and may come into contention as injuries and suspensions start to hit Ayr's squad.
Ayr have also met Morton in the Betfred Cup this season. They won 3-1 at Somerset Park thanks to a second half hat-trick from Lawrence Shankland.
