O'Driscoll told the club's official website: "He's played in the Scottish Premier League for a couple of seasons and now wants to try his hand here and everybody wants to come and play in England to see if they can.
"The Championship will be a good test for him and we could have waited until the end of the season but to be fair to Hibernian, we have done a deal that suits everybody in the sense that they get something for him and we'll pay a little but more if we stay up, a little bit more when he plays a few games for us.
"It just works for us. We can't go out and spend £200,000 or £300,000 on players, so the odd 50 grand here and there is better.
"He's a good age at 24, technically very good, so we hope he will improve the squad."
