QPR goalkeeper Julio Cesar is rated doubtful for the Premier League clash with Aston Villa at Loftus Road.
Cesar was replaced at half time of the goalless draw with Sunderland in midweek after sustaining a minor groin tear.
Rob Green will continue to deputise if Cesar fails to recover, while strikers Bobby Zamora (hip) and Andrew Johnson (knee) are longer-term concerns.
Aston Villa left-back Enda Stevens has been ruled out of tomorrow's Barclays Premier League clash at QPR with the ankle injury suffered during the midweek win over Reading.
