The 24-year-old striker joined from Wolves on an initial 93-day loan, although Millen admits the deal could become permanent in the summer should he impress.
"It's a loan, but I've said to him that if he fits in, does well for us and enjoys his time here, we could be in the market for a centre-forward in the summer," he told the Evening Post.
"That is the way I like loans to be. I want the player to know there could be something at the end of it, because that gives them an incentive."
