Blackburn and Shrewsbury picked up vital victories in their respective Sky Bet League One promotion charges.

The pair were pushed all the way in their games but remain in the hunt for automatic promotion to the second tier.

Rovers won 2-1 at MK Dons as Adam Armstrong hit a first-half brace, Tony Mowbray’s side seeing out the victory despite the hosts – who drop into the relegation zone – pulling one back through Peter Pawlett.

Shrewsbury also won a close-fought contest as they saw off Oxford 3-2 at New Meadow with Shaun Whalley scoring twice for the hosts.

Jon Nolan also got onto the scoresheet for Paul Hurst’s men as Wes Thomas and Joe Rothwell goals gave Oxford a chance of a positive result.

Charlton made it three wins out of three for Lee Bowyer as they beat fourth-place Rotherham 3-1 at the Valley to move into the play-off places.

Michal Zyro opened the scoring for the Addicks and Joe Aribo scored twice before Richard Wood registered a consolation for out-of-form Rotherham.

Peterborough also entered the play-off positions, moving up to fifth with a 2-0 win against Jimmy Floyd Hasselbaink’s beleaguered Northampton.

Jack Baldwin and Jack Marriott scored the goals to secure three points for Posh, while Ash Taylor’s late red card for Northampton only added extra gloom as they are now nine games without a win.

Both Charlton and Peterborough took advantage of Scunthorpe’s game at home to Plymouth being called off due to a waterlogged pitch, the Iron dropping to seventh as a result.

Walsall’s trip to Bradford and Doncaster’s home clash with AFC Wimbledon also fell foul of the weather.

Oldham gave their survival hopes a boost with a late comeback win over Blackpool.

Kyle Vassell had given the visitors the lead at Boundary Park but goals from Jack Byrne and Eoin Doyle, the latter with just five minutes remaining, were enough to take Oldham a point clear of MK Dons.

Southend thrashed 10-man Gillingham as Michael Turner, Theo Robinson, Michael Kightly and Stephen McLaughlin all struck in the first half of a convincing 4-0 win.

Gillingham lost Lee Martin to a red card issued on the stroke of half-time and never looked like getting back into the game.

Fleetwood also beat 10 men as they hit two late goals to win 2-0 at home to Bristol Rovers, Ashley Hunter and Jordy Hiwula scoring inside the last 12 minutes following Chris Lines’ red card for double dissent.
