Rotherham could give a debut to forward Izzy Brown, who joined on loan from Chelsea earlier this week.
On-loan midfielder Jake Forster-Caskey could return after being ineligible to face his parent club Brighton.
Brentford forward Lasse Vibe is available to return, having missed the start of the season while captaining Denmark at the Olympic Games.
Defender Yoann Barbet (ankle) is a doubt while midfielder Alan McCormack (heel) will miss the trip.
Midfielder Lewis Macleod is expected to be fit after suffering an ankle knock in midweek while goalkeeper Jack Bonham (back) will be assessed.
BBC Radio London’s Billy Reeves: “Brentford boss Dean Smith is hoping to bring in a couple more players before the transfer window closes, but it’s unlikely they’ll arrive in time for the trip to Rotherham.
“The New York Stadium will bring back nightmares for striker Scott Hogan. In September 2014 he damaged ligaments in his knee immediately after coming on as a sub on his league debut for the Bees and didn’t return to competitive football until the back end of last season.
“Brentford have been inconsistent this season so far, but currently sit sixth in the nascent table just behind west London rivals Fulham and QPR.”
Rotherham have only lost one of their last five home games against the Bees in the second tier (won two, drawn two), winning most recently in February 2016.
Brentford have won three of their last four games against the Millers (lost one).
Rotherham’s winless run in the Championship now stands at eight matches (drawn four, lost four), losing the last two by 3-0 scorelines.
Scott Hogan has scored eight goals in his last seven Championship appearances for Brentford.
The Millers have shipped 13 goals in their last four games, having conceded as many in the 16 league games before that.
The Bees have lost just two of their last 12 matches in the Championship (won nine, drawn one).
