QPR will assess Jermaine Jenas after he suffered a recurrence of a hamstring injury in the 5-2 win over Nottingham Forest.
The midfielder hobbled off just 16 minutes into the victory at Loftus Road.
Junior Hoilett was also substituted late on as Rangers looked to protect their key players ahead of the play-offs.
QPR assistant manager Kevin Bond said: “Jermaine had a bit of a problem with his hamstring and Junior had a bit of tightness. Games in quick succession have probably taken a bit of a toll on him.
“As soon as they look like they’re feeling it, you look to take them off if you can.
“You need everybody fit and fresh [for the play-offs] but you need to go in there confident so it means you can’t take liberties with the games that you play and the teams that you pick, so it’s a difficult one. The manager will need to balance all that out.”
Bond admitted he was surprised by the emphatic nature of the scoreline, with Rangers netting three times in the last 10 minutes after a fairly even game.
He said: “I didn’t see it being what it was with 10 minutes to go, I’ve got to be honest.
“Bobby [Zamora] made the difference for us when he came on, although Charlie [Austin] was terrific.
“We got undone with a couple of corners. That was disappointing and it’s something we shall look at.”
