Watford striker Danny Graham is fit to face Forest.
Graham was replaced at half-time of last weekend's 4-1 defeat at Derby after struggling with a back injury, but is expected to start again as the Hornets look for a return to winning ways.
Full-back Lee Hodson also has a back injury and is a doubt, while Scottish winger Don Cowie is still unavailable due to a knee injury.
Midfielder Ross Jenkins has recovered from an ankle problem and is in line to be involved along with 19-year-old Matthew Whichelow, who scored his first career goal as a substitute at Pride Park last week.
The Hornets have slipped to ninth in the league after successive defeats but a win could send them as high as fourth place.
Joel Lynch returns to the reckoning for Forest.
The full-back missed the defeat at Portsmouth due to illness but is fit again after a midweek run-out for the reserves.
His return presents boss Billy Davies with the rare conundrum of a full squad to select from.
Striker Robert Earnshaw made his first appearance since mid-September against Pompey after recovering from a calf complaint and will hope to start.
The same goes for Ryan Bertrand, who had to settle for a place on the bench at Fratton Park on his return from a one-match suspension.
Midfielder Guy Moussi and forwards Dexter Blackstock, Dele Adebola and Nathan Tyson are other options available to Davies should he wish to make changes.
