Huddersfield v Bolton
Huddersfield midfielder Adam Clayton will miss out at Bolton through suspension, but manager Mark Robins has no other selection problems.
Clayton reached 10 yellow cards for the season in Saturday's home defeat to Hull and starts a two-game ban, so Scott Arfield and Chris Atkinson could come into contention.
Otherwise, Robins will choose from an unchanged squad with winger Danny Ward, strikers Theo Robinson, Sean Scannell and Lee Novak, plus defenders Calum Woods and Murray Wallace all pushing for recalls.
Defender Joel Lynch missed out altogether on Saturday and could be recalled to the squad.
Midfielder Keith Southern is making good progress, but remains sidelined as he recovers from a long-term Achilles injury.
The Terriers, two points above the bottom three, have won three and lost three of their last six league matches.
Brighton v Charlton
Tomasz Kuszczak, Liam Bridcutt and Adam El-Abd return to the Brighton squad for the visit of Charlton.
Goalkeeper Kuszczak and midfielder Bridcutt missed Saturday's 2-2 draw at Nottingham Forest through illness and have now fully recovered, while Egypt defender El-Abd is available again after a two-game suspension.
Kuszczak will replace Casper Ankergren in goal after his error gifted Forest their late equaliser.
Inigo Calderon continues at right-back as fellow Spaniard Bruno is still sidelined due to a calf muscle problem, with Brighton hopeful he will be fit in about a week.
Strikers Craig Mackail-Smith (Achilles) and Will Hoskins (knee) are also injured and Ashley Barnes is still suspended following his red card for tripping the referee at Bolton last month.
Charlton will check on Matt Taylor and Dale Stephens ahead of the trip to Brighton.
Defender Taylor and midfielder Stephens missed Saturday's thrilling 3-2 comeback win over Bolton due to illness.
Striker Ricardo Fuller popped his shoulder out during the match but boss Chris Powell expects him to be fine.
Mark Gower came on as a substitute to make his debut following his recent loan switch from Swansea so he is pushing for a start.
Fellow midfielder Andy Hughes made his first start since November 2011 after a long-term Achilles problem, so he could make way.
Defender Leon Cort remains a doubt with a knee injury and midfielder Danny Hollands is still on the sidelines with a fractured metatarsal.
Middlesbrough v Peterborough
Middlesbrough midfielder Josh McEachran could return to the starting line-up against Peterborough.
McEachran, on loan from Chelsea, was back on the bench as an unused substitute in Saturday's defeat at Wolves following an ankle injury.
But striker Emmanuel Ledesma will not be included in manager Tony Mowbray's plans.
The Argentinian striker, who has missed the last two games, is struggling with an ankle problem.
Defender Stuart Parnaby (hamstring) could be included in the squad after returning to training last week, but midfielder Julio Arca is out for the rest of the season due to a toe injury.
Boro, who have lost their last four matches, have taken only seven points out of a possible 42 this year and are six points adrift of the play-offs.
Peterborough will check on Michael Bostwick before travelling to Middlesbrough.
Midfielder Bostwick, who has been playing as a centre-half, was forced off with a hamstring problem during the second half of Posh's 1-0 win at Blackpool prior to the international break and had still not recovered in time for the visit of Cardiff on Saturday.
Bostwick was rated at 50/50 ahead of the 2-1 victory over the npower Championship leaders.
Florent Cuvelier was included in the squad against Cardiff but the on-loan Stoke midfielder did not make it off the bench and will hope to make his debut at the Riverside.
On-loan midfielders Davide Petrucci and Alex Pritchard (ankle) are still not fit, with the former having returned to Manchester United after failing to recover from a hamstring injury.
Watford v Hull
Gianfranco Zola has plenty to ponder ahead of Watford's crunch trip to promotion rivals Hull.
Defender Marco Cassetti limped off early in the second half of Good Friday's 3-3 draw at home to Burnley and will be assessed, with Lloyd Doyley on standby to start from the off having replaced the Italian.
Playmaker Almen Abdi recovered from his groin injury to start against the Clarets but goalkeeper Manuel Almunia (hamstring) missed his fifth match in succession and will again be monitored ahead of the clash at the KC Stadium.
Zola made five changes against Burnley from last time out - with Championship Player of the Year Matej Vydra certain to be recalled to face the Tigers having been rested to the bench.
Defenders Nyron Nosworthy (Achilles), Neuton (dislocated shoulder) and Tommie Hoban (ankle) as well as midfielder John Eustace (back) all continue to miss out.
Hull manager Steve Bruce is hoping to have midfielder Stephen Quinn back in contention for Tuesday night's crunch clash at automatic promotion rivals Watford.
Quinn twisted his knee during training on Thursday and missed Saturday's win at Huddersfield.
Meanwhile, Bruce reaffirmed that a two-year contract has already been agreed with matchwinner George Boyd, who scored his fourth goal in six appearances for the Tigers since arriving from Peterborough in an initial loan deal last month.
