Sheffield United have admitted defeat in their attempts to sign Rangers duo Kyle Hutton and John Fleck on loan.
The Gers pair, both 20, thought they had sealed season-long moves to Bramall Lane late on transfer deadline day, with the switch confirmed by the Scottish champions.
However, the youngsters were not registered in time with the English Football League and will now stay put.
Sheffield United director Scott McCabe told the club's official website: "It has been a very frustrating time for all concerned.
"Everyone in the football administration team at the club has worked very hard to try and make these transfers happen, but we have had to eventually admit defeat.
"We had expected the transfers to go through and were surprised when we were told they had not been completed in time.
"The manager will now move on to other targets. It is the case that transfers can break down for many reasons, so Danny [Wilson] will already have in mind other options to strengthen our squad."
