Ferguson admitted that the former Leeds striker was reluctant to join the Welsh outfit.
Ferguson told Sky Sports News: “They phoned us yesterday morning and I thought about it.
“Due to the fact we are no longer in the League Cup, I thought a short-term loan would be ideal for him to get him games.
“I put it to him, and I don’t think he’s spoken to David Jones, but he has spoken to someone at Cardiff.
“I think he’s uncertain about what to do, he’s not sure whether to take it or not. It’s an option to play games, that was merely the idea from our part. With us not being in the League Cup, it’s a good opportunity to get games as he really needs football.”
