Brazilian defender Emilson Cribari is nearing a return from a groin injury, while Dean Shiels made his first start since March last week after recovering from a serious knee problem.
But McCoist will give serious thought to whether he should include the duo against the Diamonds due to the surface.
The Light Blues boss is already restricted to fielding just two of his new signings as trialists in the match as the club waits for a transfer embargo to end on September 1.
McCoist told the Rangers website: "The park is something that's part and parcel of facing some teams in the lower leagues and we have to get used to that.
"I've made my view on artificial surfaces clear - I'm not a fan of them.
"You do get some that are better than others, but, generally speaking, I'm a believer football should be played on grass.
"We've played on these types of pitches enough now though to know what to expect and it's a little bit of a leveller.
"The surface will play a big part in who we bring back tomorrow and we'll have to take a look at Emilson.
"He is coming along nicely but I have to take the pitch into account.
"I'll maybe have a wee chat with Shielsy as well. He's fit but he's just coming back from an injury.
"Let's not forget David [Templeton] also suffered a very serious injury on that kind of pitch down at Annan last year.
"There are a lot of things to weigh up."
