Joel Lynch is a doubt for Queens Park Rangers' FA Cup fifth-round tie at home to Watford on Friday night.

The defender will need to be checked after missing the midweek defeat at Bristol City with a back problem.

Rangers boss Steve McClaren has a couple of unnamed players carrying knocks, but will have to make do without Angel Rangel and Geoff Cameron.

Right-back Rangel has a thigh problem while the versatile Cameron, who can play in defence or midfield, is struggling with an ankle injury.

Sebastian Prodl and Roberto Pereyra could feature for Watford after returning to training.

Defender Prodl is back from a knee problem while midfielder Pereyra has recovered from a hamstring issue.

Hornets boss Javi Gracia made 11 changes in the last two rounds, but may be tempted to keep tweaks to a minimum as his side look to book a quarter-final spot.

But Gracia will be unable to call on injured pair Isaac Success and Kiko Femenia.

Merson's prediction

I've got Watford down as my dark horses for the cup. I don't see why Watford don't [play a full strength line-up]. Man Utd are playing Chelsea and another good team is going out. It makes me laugh but that's up to them because for me I'd play a strong team now.

They should have enough to beat QPR. I think it will be a free hit for them. QPR have hit a bit of a brick wall. They have done great, got out of trouble then went on a run and have got quite near the play-offs.

Merson's FA Cup predictions

Chelsea, Man Utd, Man City and Watford in action - but who is the Magic Man backing?

QPR have dipped down again but they've got home advantage, they'll be looking forward to it. They will know Watford will make changes. For me they should be playing a strong team but they probably won't. I still think Watford will just have too much.
