Chelsea v QPR preview
Chelsea goalkeeper Petr Cech is expected to miss the visit of QPR after injuring himself in Sunday's win at Everton.
The Czech Republic international was forced off at half-time with an adductor problem and his replacement Ross Turnbull will deputise at Stamford Bridge.
Midfielder John Obi Mikel missed the Goodison Park victory with a knee injury but it is not deemed serious by manger Rafael Benitez.
QPR boss Harry Redknapp has admitted he will be without three or four players for the short trip to face Chelsea.
Redknapp says a number of his squad picked up knocks during Sunday's 3-0 loss to Liverpool but refused to give away any names.
Park Ji-sung returned to training on Monday but remains a major doubt as he recovers from a knee problem, while strikers Andrew Johnson (knee) and Bobby Zamora (hip) are sidelined with long-term injuries.
