Simpson blow for Rangers
QPR will be without Danny Simpson when they host Bolton.
Right-back Simpson misses his first game of the season - and faces a few weeks on the sidelines - after suffering a back injury so manager Harry Redknapp has recalled youngster Max Ehmer from his loan spell at Carlisle as cover.
Joey Barton remains a doubt after missing the recent 2-1 win over Huddersfield with a thigh problem while fellow midfielder Jermaine Jenas and defender Nedum Onuoha are also short of fitness.
But winger Junior Hoilett could return to the squad after a spell out with hamstring trouble.
Goalkeeper Andy Lonergan will retain his place in the starting line-up at QPR, despite committing the error which knocked Bolton out of the FA Cup at the weekend.
The stopper spilled the ball to allow Frazier Campbell to score Cardiff's only goal at the Reebok Stadium but, even though Adam Bogdan is now fit again following a knee injury, Wanderers boss Dougie Freedman insists he will stick with Lonergan.
Freedman also confirmed Mark Davies will come back into the reckoning after being rested against the Bluebirds - the midfielder is only just back from a long-term knee problem.
Craig Davies may start up front once more after David Ngog completed his move to Swansea on Monday, while Stuart Holden (knee) will this week return to the United States for the latest part of his rehabilitation.
