Leeds United have signed Celtic's Irish centre-half Darren O'Dea on a season-long loan.
O'Dea, 24, spent the whole of last season in the Championship with Ipswich Town and has previously played in the division with Reading.
He told the club website: "I'm delighted to be here. I'd been looking to get away and as soon as I heard of Leeds' interest I had no doubts.
"I'm hoping to achieve what everyone here is hoping to achieve - promotion."
