QPR will this week look to sign a goalkeeper on an emergency loan after David Marshall injured his hamstring in the 3-1 defeat at Nottingham Forest.
Three second-half goals, including two in the final seven minutes, saw Rangers sink to defeat after taking the lead thorough Andre Gray in the first half.
Rangers ended the match with 10 men, and Lee Wallace in goal, after Marshall went off after all three substitutions had been made.
The injury to Marshall looms as a serious problem, with keepers Seny Dieng, Jordan Archer and Joe Walsh also sidelined.
EFL rules prevented Rangers from bringing in extra cover before Marshall’s injury.
And with Premier League clubs not allowed to loan players out, the club face a race against time to find a keeper for Sunday’s match against Peterborough.
Manager Mark Warburton says they may have to look to teams outside the Championship for emergency cover.
“David has said to us he has never had a muscle injury in his career. He made a fantastic save where he dived low to the corner, but unfortunately that made it worse,” Warburton said.
“We had used our subs up and we hoped we could deal with it and get through the game but obviously we now have an issue.
“We had four wing-backs out earlier in the season, which is quite remarkable, and now we have four goalkeepers out. I have never seen anything like it in my life.
“We have to look at the options and we have to move quickly because we play on Sunday.
“We can sign emergency goalkeepers outside of the transfer window, but not from the Premier League. I am not sure if many clubs in the Championship are going to want to help us.
“Phone calls are being made now to see what is available.”
Rangers also lost Chris Willock to a hamstring injury in the first half, which really hampered their attacking game as Forest struggled to deal with his threat before he limped off after half an hour.
“I thought he was in really good form,” Warburton said.
“We wanted Andre (Gray) to stretch them and Chris to pick the ball up deeper and drive at them, which is what he was doing.
“He was enjoying himself, looking dangerous, and they were not happy trying to deal with him.
“He got a kick to the back of the hamstring – innocuous really. We have certainly paid the price tonight.”
