Brighton will be without Gonzalo Jara Reyes for the visit of Derby. The Chilean defender starts a three-match ban after he was sent off during Saturday's 3-1 defeat at Blackpool. Inigo Calderon is a natural replacement at right-back although Adam El-Abd could move across from centre-half with Lewis Dunk or fit-again Marcos Painter (hamstring) returning to the back four. Winger Gai Assulin, who missed out at Bloomfield Road with a slight groin strain, could be involved if, as expected, he extends his loan deal from Manchester City until the end of the season. Midfielder Gary Dicker is pushing to be involved after recovering from a broken leg so defender Tommy Elphick is the only long-term absentee with an Achilles injury.
Derby have no new problems ahead of the trip to Brighton. Rookie defender Tom Naylor made his full debut at Doncaster on Saturday as boss Nigel Clough made three changes. Naylor, signed from Mansfield in November, lined up at right-back, allowing former Rovers man Paul Green to move up into midfield. Forward Jamie Ward remains around 10 days away from a return after missing five matches with a thigh injury sustained on international duty with Northern Ireland.
Bristol City welcome Watford to Ashton Gate but will again be without defender Lewin Nyatanga. The Robins will be without the centre-back for a further three weeks due to his persistent ankle injury. The Wales international has had an injection to try and cure the problem, but it will not be a quick solution. Manager Derek McInnes will be without the services of on-loan midfielder Sean Davis as a thigh strain keeps him out and the Bolton man is fighting to be fit for the weekend game at Middlesbrough. Another player who could miss both games is on-loan Boro defender Stephen McManus. The former Celtic man rolled his ankle at the weekend and the Robins will assess him before making a decision. Marvin Elliott (Achilles), striker David Clarkson (ankle), Cole Skuse (broken toe) and James Wilson (ankle) are all out.
Adrian Mariappa and Alex Kacaniklic are doubts for Watford's trip to Bristol City. Centre-back Mariappa finished Saturday's stalemate against Coventry with an ankle injury and faces a race against time to be fit for the clash at Ashton Gate. Winger Kacaniklic is expected to have a better chance of involvement, however, despite being forced off 10 minutes from time with a leg problem.
Doncaster defender Tommy Spurr is set to face Millwall despite learning he will need an operation on his broken hand. Former Sheffield Wednesday full-back Spurr is set to have surgery at the end of the season, but Rovers boss Dean Saunders is confident he can be patched up to play his part in the club's fight for Championship survival. Shelton Martis is an injury doubt for Saunders once more. The centre-back returned in Saturday's 2-1 defeat to Derby but was withdrawn in the second half due to soreness in his hamstring and calf. Captain Brian Stock is a fortnight away from returning from a torn groin muscle, while fellow midfielder Martin Woods remains absent despite having a painkilling injection in his knee.
Millwall will check on skipper Paul Robinson ahead of the trip to fellow strugglers Doncaster. Centre-half Robinson scored his first goal in more than a year against Southampton on Saturday but finished the 3-2 defeat carrying an ankle knock. Midfielder Liam Trotter will miss out again with a thigh injury which is expected to sideline him for another fortnight. With Therry Racon (ankle) out for the season and Tamika Mkandawire (knee) still missing, boss Kenny Jackett is short in midfield and is likely to give a debut to new loan signing Sheffield United's Nick Montgomery. Defender Shane Lowry is expected to miss out again with an ankle problem and back-up goalkeeper Steve Mildenhall (ankle) is also in the treatment room.
Hull midfielder Corry Evans is doubtful for the home game with Southampton due to a minor hamstring injury. The Northern Ireland international was replaced at half-time during Saturday's goalless draw at Crystal Palace and replaced by Tom Cairney, who will continue if Evans fails a late fitness test. Winger Robbie Brady overcame a recurring thigh problem to step off the substitutes' bench in place of Josh King midway through the second half against Palace and could be pushing for a return to the starting line-up. Striker Matty Fryatt is another player hoping for a recall after starting the last two games on the bench, while manager Nick Barmby has no other selection issues.
Southampton will check on Tadanari Lee ahead of the trip to Hull. Japanese striker Lee missed Saturday's dramatic 3-2 win at Millwall with an ankle injury and could be forced to sit out again. The leaders are otherwise at full strength with boss Nigel Adkins likely to make one or two changes for the midweek clash.
Leeds boss Neil Warnock will pick his starting line-up for the home game with Nottingham Forest from an unchanged squad for the second match running. Alex Bruce (hamstring) is close to a return to full training and another versatile defender, Leigh Bromby (knock), is not far behind, but neither will be ready in time for Tuesday night.
Nottingham Forest could have Danny Higginbotham and George Elokobi available when they resume Championship action against Leeds at Elland Road. Higginbotham missed the late defeat to East Midlands rivals Derby a week ago because of a hamstring problem. Fellow on-loan defender Elokobi has sat out the last two matches with a similar injury. Marcus Tudgay will be absent through suspension. The striker was sent off for two bookable offences against his former club at Pride Park and must serve a one-match suspension.
Peterborough will check on skipper Grant McCann and defender Gaby Zakuani ahead of the visit of in-form Reading. McCann limped out of the defeat to Ipswich on Saturday with 12 minutes remaining because of a calf strain and the Northern Ireland international midfielder will be assessed. Zakuani has been playing through the pain barrier for several weeks now and once again completed the full 90 minutes at Portman Road despite his ongoing toe problem.
Reading will monitor the fitness of Jem Karacan ahead of their trip to Peterborough. The midfielder was substituted in the 4-0 win over Barnsley following a nasty challenge, but the move was more precautionary than necessary. New loan signing Hayden Mullins made his debut at right-back in the win and could fill the same role again for Brian McDermott's side. The Royals were boosted by the return of Malian winger Jimmy Kebe to the squad, although after overcoming a knee injury, he may not be asked to play two games in three days.
Portsmouth have no new injury concerns ahead of the visit of Birmingham. Striker Dave Kitson was dropped from the squad which drew 0-0 with Bristol City on Saturday and could return with Pompey having scored just once in their last seven outings. But manager Michael Appleton otherwise has little room to freshen up his side following the recent departures of Erik Huseklepp, Liam Lawrence, Hayden Mullins and Stephen Henderson to trim the wage bill.
Peter Ramage is expected to be fit as Birmingham continue their promotion push at bottom-club Portsmouth. The full-back was replaced after 53 minutes of Saturday's 3-0 victory over Middlesbrough having struggled with tonsillitis all week, ensuring Blues finished a second successive match with three recognised centre-backs across defence. Ramage's expected recovery for the trip to Fratton Park is a welcome boost with right-backs Jonathan Spector (thigh) and Stephen Carr (knee) already ruled out for the immediate future. Left-back David Murphy made a welcome return from his hip problem to start against Boro and will again be available, easing manager Chris Hughton's problems at full-back. On-loan striker Erik Huseklepp is ineligible to face his parent club while midfielder Jordon Mutch serves the final game of his three-match suspension.
James Tomkins is West Ham's latest injury worry ahead of the visit of Middlesbrough. The England Under-21 international had to come off during Saturday's 1-1 draw at Leeds due to a calf problem and is set to miss out. Tomkins, usually a centre-half, has been playing in midfield as Papa Bouba Diop remains sidelined with a hamstring injury. Winger Ricardo Vaz Te will be out for at least another week with his hamstring problem while Winston Reid (head),Julien Faubert (groin) and Guy Demel (thigh) are still carrying knocks. Ravel Morrison, who made his first Hammers appearance as a late substitute at Elland Road, could therefore be in line for a full debut while Gary O'Neil is also on standby.
Middlesbrough boss Tony Mowbray will be without influential midfielder Barry Robson once again for Tuesday's Championship trip to West Ham. The Scotland international will sit out the second instalment of the three-match ban be picked up for his sending-off in the 2-0 home defeat by Leeds. Utility man Rhys Williams will also be missing as he recovers from the ankle ligament problem he suffered during the same game. Faris Haroun's hamstring injury continues to be assessed, but he remains a doubt for the game at Upton Park. Goalkeeper Danny Coyne is back in training after a calf problem, but striker Scott McDonald, while making good progress, continues his rehabilitation for medial ligament damage.
Crystal Palace will check on Darren Ambrose ahead of the home game against Barnsley. Eight-goal midfielder Ambrose was ruled out of Saturday's goalless draw with Hull due to an illness. Winger Wilfried Zaha serves the second game of his three-match ban for his red card against Burnley last weekend. In the absence of Ambrose and Zaha, Dean Moxey and Jonathan Williams came into the Eagles side on Saturday following long lay-offs.
Barnsley manager Keith Hill could recall teenage midfielder Paul Digby to his side at Crystal Palace. The 17-year-old, handed his first professional contract last week, has been used sparingly by Hill since making his debut against Birmingham last month. But the Tykes have won only one of their last nine league matches and Hill may want to make changes. Two more academy products, winger Reuben Noble-Lazarus and centre-half John Stones, who made his debut off the substitutes' bench against Reading, are hoping to be involved again.
