Luke O'Brien could makes his Exeter debut.

The full-back arrived at St James' Park from Bradford on transfer deadline day but was not part of the matchday squad that lost 2-0 at Bournemouth on Tuesday.

O'Brien will compete with Billy Jones for the left-back position, and manager Paul Tisdale otherwise has a fully-fit squad at his disposal.

After extending his loan from Reading by a further month, Jake Taylor could return to the starting line-up in attack after coming off the bench against the Cherries in midweek, while Liam Sercombe has recovered from injury.

Midfielder Sercombe could also come back into the side in place of Scot Bennett, as Exeter host the Owls chasing their first victory - and their first goal - in five League One matches.

Sheffield Wednesday manager Gary Megson must decide whether to recall defender Miguel Llera or retain skipper Rob Jones at the heart of defence.

Jones returned for the midweek FA Cup defeat to Blackpool after missing the previous four games due to an ankle injury while on-loan Llera was ineligible to play against his parent club.

Megson made seven changes for the fourth-round replay on Tuesday night and is expected to revert back to something similar to the side that started in last week's league match against Yeovil.

John Bostock, on loan from Tottenham, is likely to be recalled, as is fellow midfielder David Prutton, while winger Jermaine Johnson, who has scored three goals in his last five games, will return after being rested.

Strikers Gary Madine and Chris O'Grady are also likely to return to the starting XI as the Owls bid to extend their unbeaten away record in the league to four matches.

Hartlepool manager Neale Cooper is expected to name an unchanged side for the home clash, which passed a 12noon pitch inspection on Friday.

Cooper has no new injury or suspension problems as his side look to build on last week's 4-0 home win over Carlisle and stretch their unbeaten league run to five matches.

But striker James Poole, sidelined since Boxing Day due to a hamstring injury, must wait a while longer for his comeback.

The summer signing from Manchester City had an epidural injection after consulting a specialist on Wednesday and is hoping to return to training next week.

Another striker, Colin Larkin (knee), remains a long-term absentee and although Colin Nish is pushing for a return to the starting line-up, Cooper is expected to stick with James Brown and teenager Luke James - three goals in his last four appearances - up front.

Bournemouth will be without midfielder Wes Fogden.

Fogden suffered an ankle injury during the 1-0 defeat at Chesterfield on January 27 and will not be fit enough to line up against Pools.

Matt Tubbs will keep his place up front after netting on his debut against Exeter in midweek, while Scott Malone will be pushing for a start after coming off the bench to score the second goal in the 2-0 victory over the Grecians following his return from injury.

Manager Lee Bradbury will be missing captain Adam Barrett, however, who has been ruled out with a hamstring problem, while Mathieu Baudry (hamstring), Joe Partington, Shaun Cooper, Mark Molesley and Nathan Byrne (ankle) are still short of match fitness.

Striker Charlie Sheringham will miss the rest of the season with a foot injury, while goalkeeper Shwan Jalal has been sidelined for six weeks after undergoing a routine back operation.

Sheffield United manager Danny Wilson must decide whether to hand new striker Will Hoskins a place in his starting line-up.

Hoskins, signed on loan from Brighton until the end of the season, was denied a debut last week as the Blades' league clash at Colchester was postponed.

Richard Cresswell has been partnering leading goalscorer Ched Evans in recent weeks and Hoskins may have to settle for a place among the substitutes.

Another striker, James Beattie, sits out the second game of a three-match ban but midfielder Nick Montgomery is expected to return to contention following an ankle injury.

Marcus Williams is pushing for a starting place at left-back after replacing Lecsinel Jean-Francois for the last 30 minutes in the last outing, a 4-0 home FA Cup defeat to Birmingham.

Stuart Lewis will hope to regain his place in the Wycombe team.

Lewis found himself in the unfamiliar surroundings of the substitutes' bench against Tranmere.

The 24-year-old has been a regular pick in midfield for Wanderers since joining the club on loan from Dagenham last season and then signing a permanent deal in the summer.

He made his debut from the bench in November 2010 but had since started every game - barring injury or suspension - until last weekend when he was rested.

On loan Watford striker Matty Whichelow is likely to keep his place in the side after scoring on his debut in the 2-1 win over Tranmere.

Defender James Tunnicliffe has joined Crewe on a month-long loan deal.

Peterborough's Championship match against West Ham and Barnsley's home date with Birmingham have both been postponed due to frozen pitches, this coming a day after Crystal Palace's game against Doncaster was also called off.

MK Dons' League One clash against Bury has been postponed due to a frozen pitch at stadium:mk, while Brentford's home clash with Oldham at Griffin Park is also off due to a frozen pitch. Chesterfield v Charlton, Yeovil v Scunthorpe, Leyton Orient v Huddersfield, Rochdale v Notts County, Stevenage v Carlisle, Tranmere v Preston and Walsall v Colchester are also off.

The League Two matches at AFC Wimbledon, Accrington, Barnet, Burton, Crawley, Dagenham, Macclesfield and Port Vale have also been postponed.

Postponed matches:

Championship: Barnsley v Birmingham, Peterborough v West Ham, Crystal Palace v Doncaster

League One: Brentford v Oldham, Chesterfield v Charlton, Leyton Orient v Huddersfield, MK Dons v Bury, Rochdale v Notts County, Stevenage v Carlisle, Tranmere v Preston, Walsall v Colchester, Yeovil v Scunthorpe

League Two: AFC Wimbledon v Bradford City, Accrington v Oxford United, Barnet v Swindon, Burton v Gillingham, Crawley v Aldershot, Dagenham & Redbridge v Northampton, Macclesfield v Plymouth, Port Vale v Crewe

Powell guided his side to four wins and a draw last month as the Addicks maintained their place at the summit of League One to remain on course for a long-awaited return to the Championship.

Midfielder Jackson, 29, proved to be a real matchwinner for the London outfit, with the only goal in both 1-0 victories over Sheffield Wednesday and Sheffield United.
