Nottingham Forest have taken Clint Hill on a 93-day emergency loan from Queens Park Rangers after learning that Chris Cohen is to be sidelined for the foreseeable future.
The Reds have found themselves short of defensive cover this season, especially at left-back.
Cohen had been filling in, but he suffered a serious injury during Forest's 2-1 defeat to arch-rivals Derby on Saturday.
Scans have revealed that he has suffered cruciate ligament damage in his right knee and he will be out of action for a prolonged period of time.
Steve McClaren was already in the market for loan cover and has moved quickly to snap up Hill.
The 32-year-old, who can operate at centre-half or at left-back, will link up with the Reds later this week and could be in line to make his debut in Saturday's trip to Watford.
McClaren told the club's official website: "It's a bitter blow for Chris who has been one of our stand-out performers so far this season but we are delighted to have agreed terms with QPR for Clint.
"He has great experience and will add to our defensive options."
Hill figured in all but two of QPR's Championship fixtures last season as they landed the second tier title.
He was named in Neil Warnock's starting XI on the opening day of the new Premier League campaign, but has been overlooked since being dismissed in a heavy defeat to Bolton.
