Jordy De Wijs is nursing a hamstring problem following QPR’s 3-1 defeat against Norwich.
The Dutch defender, whose loan spell at Rangers has been blighted by injuries, returned to the side having missed two matches since recently suffering a broken nose.
De Wijs has previously been out with calf and groin problems.
And he was taken off with 16 minutes remaining against the Canaries.
“It was a bit of tightening in the hamstring. We had to be precautionary,” said Mark Warburton.
Rangers manager Warburton earlier made a change at half-time, taking off George Thomas and sending on Sam Field in order to give Stefan Johansen better support in midfield.
Warburton said: “I’m very pleased with George and his performances over the last few games.
“Any player will be disappointed to be substituted at half-time but you tell them the truth; it was a tactical change as Stef was isolated in midfield.
“We were giving their front players too much time and space. We had to get tighter and get another body in there.
“In the second half I thought we looked much better. We were much more solid and compact.”
