Watford boss Sean Dyche has no fresh injury or suspension concerns and could well stick with the same starting line-up for the fourth successive match.
The Hornets were below par last weekend but still came away from Barnsley with a point from a 1-1 draw, extending their unbeaten sequence to four league matches.
Strikers Chris Iwelumo and Joe Garner both got 45 minutes under their belts in a midweek friendly defeat to QPR and will be pushing for involvement.
Garner is yet to start a first-team match since his deadline-day switch from Saturday's opponents Forest, although he has stepped off the bench in both games since his arrival.
Defender Lee Hodson and midfielder Stephen McGinn (knee) continue to be the only absentees for the 5.15pm kick-off.
Clint Hill is expected to make his debut for Forest.
Hill, who can play at centre-half or left-back, has been brought in on a 93-day emergency loan from QPR following a serious injury to Chris Cohen.
Cohen, who usually plays in midfield but has started the season as a full-back, faces around a year out after suffering knee ligament damage during the home defeat to East Midlands rivals Derby last weekend. Hill is likely to replace him in the starting XI at left-back.
Cohen joins midfielders George Boateng (ankle) and Paul Anderson (hamstring) and forwards Garath McCleary and Dexter Blackstock (both knee) on the sidelines.
Brendan Moloney, Lewis McGugan, Robbie Findley and Marcus Tudgay, who all came into the side for the Carling Cup defeat to Newcastle, will be hoping to have done enough to retain their places.
