The Rams previously secured Liverpool defender Daniel Ayala, 20, for the rest of the season, and Derby boss Nigel Clough commented to the club website:
“Brad fits the bill perfectly. He has Premier League experience, Football League experience and most importantly big game experience.”
“We have some big games coming up between now and May and he will be our number one in them.”
“Liverpool have done us a big favour and I would like to thank Kenny Dalglish and the other officials at Anfield for agreeing to loan another of their players to Derby County.”
