QPR striker Andrew Johnson will undergo a scan after suffering a knee injury in the west London derby against Chelsea.
Johnson was substituted during the first half as was Fabio, who picked up a hamstring strain and will be assessed on Monday.
“AJ will be scanned. He felt something in his knee,” Rangers manager Mark Hughes explained.
“We’re hoping he’s going to be okay. It could be more serious but we’re hoping it’s not.”
Aside from the injuries, Hughes had every reason to be pleased with his team’s performance against their neighbours.
Rangers put Chelsea under plenty of pressure in the 0-0 draw, with Ji-sung Park and Bobby Zamora both missing chances to put them ahead in the second half.
Hughes said: “I thought we were excellent. In terms of control of the game we were able to do that effectively for long periods and that augurs well for the future given that we were up against the European champions.
“We were always looking to win the game and create chances. All in all, it’s an improvement on what we produced against Man Cty and that’s what we’re looking for.
“It’s proof that we’re going in the right direction. It’s only a matter of time before we get that first win and then really get our season going.
“Playing Chelsea on our patch was a challenge for us and we were up to it.”
