League One preview

The cold snap which wreaked havoc on the fixture list last weekend has continued, with Brentford's visit of Oldham and Bury's trip to MK Dons the first casualties.

The clash between promotion hopefuls Stevenage and Carlisle, as well as Walsall's visit of Colchester and Notts County's trip to Rochdale, have also been postponed.

Leaders Charlton will look to stretch their seven-point advantage at the top of the table when they make the trip to the B2net Stadium to face rock-bottom Chesterfield, who are three points adrift of safety.

Sheffield Wednesday maintained their promotion chase when they came from behind to beat Yeovil Town at Hillsborough last weekend and will look to close the gap on the Addicks when they travel to lowly Exeter, who are without a win in four.

The Owls' city rivals and fellow promotion hopefuls Sheffield United saw their clash at Colchester postponed last Saturday due to a frozen pitch and will look to make up ground at home to struggling Wycombe, who sit just a point clear of the relegation places.

High-flying Huddersfield are currently sandwiched between the Sheffield rivals in third place after being held to a 1-1 draw at home to MK Dons last weekend and will be keen to maintain an eight-match unbeaten run at Leyton Orient.

Play-off hopefuls

Bournemouth could climb into the play-off spots with the right result at mid-table Hartlepool, who demolished Carlisle 4-0 last time out before seeing their clash at Bury postponed last weekend.

Scunthorpe will also be pushing to climb out of the relegation places when they make the trip to Yeovil Town, still stinging from their collapse at Wednesday.

Fellow relegation candidates Rochdale entertain Notts County, who will be seeking back-to-back wins at Spotland.

Finally, Tranmere are still hunting their first victory of 2012 ahead of their visit of Preston.
