Burnley boss Brian Laws will be without defender Danny Fox for the home clash with Watford but striker Martin Paterson is hoping to be passed fit.
Fox was stretchered off with suffered suspected ankle ligament damage following a heavy fall in the second half of Tuesday's 1-1 draw at home to Doncaster.
And Paterson was replaced at half-time after picking up a thigh strain just before the break, but he has responded well to treatment.
"Danny is the more serious one," said Laws. "There is a bit of swelling there and he's certainly out for the weekend.
"Martin Paterson has made a good recovery over the last 48 hours. Fingers crossed if he continues the recovery as he is then he has a great chance for the weekend."
Central defender Andre Bikey will return after a rib injury which has seen him miss Burnley's last two games and Brian Easton is set to deputise for Fox at left-back.
