Millers monitoring Arnason
Rotherham will check on defender Kari Arnason ahead of the vital Sky Bet League One clash with Brentford.
The Iceland international suffered a knock in Saturday's 1-0 win at Peterborough and he will be assessed before kick-off at New York Stadium.
Striker Wes Thomas missed out at London Road with a thigh injury, but he is thought to be back in contention while Mark Bradley is out for the season with a knee injury.
The Millers, who are unbeaten in 13 games, have to beat the second-placed Bees if they are to have any chance of gatecrashing the automatic promotion places.
James Tarkowski returns to the Brentford squad.
The defender missed Saturday's 3-1 win over Coventry through suspension after his red card at Leyton Orient the previous weekend.
Boss Mark Warburton must decide whether to reinstate Tarkowski at centre-half or stick with Harlee Dean, who has been playing on despite a groin injury recently.
Adam Forshaw dropped to the bench on Saturday to rest a long-standing ankle problem and is set to return in midfield, but winger Sam Saunders is still recovering from knee surgery.
