Michael Kightly is set to make his Watford debut.
The winger arrived on a month-long loan from Wolves earlier this week and will go straight into the frame to face the Eagles.
Manager Sean Dyche has virtually a fully-fit squad for the encounter and boasts plenty of options as he looks to secure what would be only a second home victory this season.
Left-back Carl Dickinson missed the club's 4-0 defeat at Southampton last time out due to illness but has now fully recovered following the two-week international break.
David Mirfin replaced Dickinson to make his league debut at St Mary's, Watford's only change from their 2-1 victory over Millwall.
Defender Lee Hodson (knee) is fit once again and will battle it out to make the Hornets matchday 16, but midfielder Stephen McGinn (knee) continues to miss out and is the only absentee.
Crystal Palace could welcome back Nathaniel Clyne, Kagisho Dikgacoi and Owen Garvan for the game.
Full-back Clyne has been out all season with a foot injury, Dikgacoi suffered a hamstring problem in mid-August and fellow midfielder Garvan twisted his knee six weeks ago.
But all three resumed training this week to give boss Dougie Freedman some welcome selection dilemmas.
Clyne is slightly ahead of his two team-mates fitness-wise and could go straight back into the starting line-up in place of midfielder Jonathan Parr, who deputised at right-back in the 2-2 draw with West Ham last time out.
Left-back Lee Hills (knee) is a long-term absentee and youngster Jake Caprice picked up a knock playing for the reserves this week.
