Queens Park Rangers boss Mark Hughes has admitted that Andrew Johnson, Anton Ferdinand and Fabio could all be out for several weeks.

The trio picked up knocks in Saturday's 0-0 draw with Chelsea at Loftus Road, and Hughes has revealed his concern.

"It was a blow losing two players in the first half, because it definitely compromised us in the second period when I would have probably made changes. AJ felt something in his knee. We hope he's going to be okay but it's a little bit of a worry," he told the club's official website.

"You need players like AJ in the squad, because they give so much. We'll send him for a scan over the next few days and hopefully he'll be okay.

"Fabio has pulled his hamstring and will be out for a number of weeks, which is a blow for us. Anton felt a little bit of tightness in his hamstring but, having made all three substitutes by that stage, he just had to get through the final few minutes."

QPR sit 19th in the Premier League table.
