Owain Fon Williams is currently sidelined with injury and the speed of his recovery is likely to determine Moore's decision.
The Rovers boss has not ruled Fon Williams out of contention for Saturday's meeting with Walsall and is expected to make a decision on Tuesday.
"He's improving. I spoke to him on Sunday and it has certainly got better," Moore told the club's official website.
"We have got the opportunity to bring someone in, we've got someone lined up to do that. But I'm not going to bring him in if Fonners is going to be okay.
"We'll wait and see and I'll know more on Tuesday."
