QPR boss Mark Warburton admitted he was “less optimistic” about a quick return for Chris Willock.
rangers appalling 3-1 home defeat to Peterborough was their fourth defeat in five matches and they dropped to eighth in the table.
And their misery was compounded by a CT scan indicating Willock’s hamstring issue is worse than initially thought.
Willock limped out of the midweek defeat at Nottingham Forest and Rangers were hoping he would be fit again as soon as possible.
Stefan Johansen and Lee Wallace missed the loss to Posh with minor blows.
“It’s tough with injuries right now,” Warburton said.
“No excuses – there’s enough quality in the squad – but injuries at the moment are tough.”
Warburton admitted angry home fans had every right to mock his team after Sunday’s game.
He said, “These boos must hurt. They should hurt every player and every member of a man’s staff – and I’m sure they do.
“They care passionately about it. It will hurt. But bettors are right to boo.
A triple substitution by Warburton in the second half did not make much noise in the crowd.
Striker Luke Amos and striker Andre Gray were removed along with Andre Dozzell, with Jeff Hendrick, George Thomas and Charlie Austin sent on.
Warburton explained: “We needed someone to get on the ball. It sounded everywhere and we didn’t deal with football.
“Andre (Gray) played 90, 77 and 90 minutes and was great for us. We have to be careful. When they haven’t played so much football in a long time, all that happens is they get tired.
“We’ve suffered (injuries) this season and suffered again with Chris Willock and David Marshall, and we’ve had Lee Wallace out for weeks and Sam McCallum in surgery – you have to be very careful.
“We have an exceptional medical team. You can ignore them, but if you do, you do so at your own risk. So that was André Gray’s situation.
“Then it was about getting the energy to go forward. Luke scored a great goal, but I didn’t think we were threatening their keeper. I thought George could do that.
“I thought Jeff might be the one to get on the ball for us and George might stretch them.”
