Warren back for Airdrie Airdrie will have Australian full-back Marc Warren available to face Morton as he has now completed his two-game suspension. The Diamonds also hope to have Jack Boyle in their squad following a knock, with youngster Lee Brown included for a second time after an impressive debut as a substitute in last weekend's battling 1-1 draw with Falkirk. Scott Sally is a doubt. Manager Jimmy Boyle said: "Home games are very important to us as if we do well in them then we will do well in the First Division. "Morton have a very experienced squad but if we can take something from them and something when Hamilton visit next weekend then it will have been a decent couple of opening months to the season." Morton defender Mark McLaughlin faces a late fitness test on a knee problem ahead of the clash. Boss Allan Moore welcomes back David O'Brien and former Celtic youngster Liam Gormley will be included again as a trialist, but Martin Hardie, Kevin Rutkiewicz and Peter MacDonald remain sidelined. Moore said: "Hopefully Mark will make it as he is a real leader on the pitch and after working hard to secure a clean sheet last weekend against Raith Rovers, I don't want to unsettle our back four. "Airdrie worked hard to get a point at Falkirk last week but having won two games in a row we want to get to three and start playing with some real confidence."
