Queens Park Rangers defender Jack Robinson has been ruled out for up to 12 months with a knee injury.
Robinson, 21, joined Rangers from Liverpool in August before being loaned straight to Huddersfield Town on a season-long deal.
He made 31 appearances for the Championship side in all competitions.
"We're all extremely sad to hear of the extent of Jack's injury. He's been great for us," Terriers boss Chris Powell told the club website.
