Queens Park Rangers are waiting to discover the extent of injuries suffered by Andrew Johnson and Anton Ferdinand while Fabio da Silva has been ruled out for several weeks.
Johnson limped out of the first half of Saturday's 0-0 draw with Chelsea with a knee problem and Fabio also failed to make it to half-time due to a pulled hamstring.
Meanwhile, Ferdinand, who caused controversy before kick-off by refusing to shake hands with John Terry or Ashley Cole in an ongoing racism row, hobbled through the closing stages with a strapped hamstring.
Ferdinand was forced to play on after QPR had used all of their substitutions and manager Mark Hughes is now awaiting the results of scans on the centre-back, Johnson and Fabio, although the outlook is already bleak for the latter.
Hughes told QPR's official website: "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.
"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."
Hughes added: "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."
