Sheffield United boss Kevin Blackwell admits he was stunned by Tottenham's late recall of Kyle Walker.
Spurs chief Harry Redknapp said he wanted the England Under-20 defender back at White Hart Lane 10 minutes before the transfer window closed on Monday.
Blackwell said: "It was a late decision. The paperwork came in 10 minutes before the 5pm deadline.
"Tottenham were within their rights to recall him so I've got no complaints.
"It was a complete surprise, but then football is full of surprises."
